The EGR and solenoid are original and when I had the upper intake off a
couple of months ago I cleaned the EGR with some carb cleaner before I
reinstalled it. I read on the archives that someone's engine died while
driving and they had the EGR replaced and everything was fine.

New Walbro installed a couple of years ago, plugs, cap + rotor, fuel
filter, pcv valves all replaced within the past 6-months.

Trying to figure out if the EGR is sticking alittle or a bad EGR solenoid
would cause the above.

I had the same problem

I had the same problem

Rick-
I had the same problem, but mine would start right back up.
It was strange though as it would die when I was letting off the gas,
applying the brakes and turning. Very scary to be turning and the truck dies and you have no power steering... :eek:
I did replace the egr and had no further problems.
HTH.

Rick,

I had a similiar thing only different. I wasn't the one who found the issue - my dad did so pardon the lack of details. Supposedly where the main power plugs into the fuse box had come disconnected - but not all the way. It didn't give me any codes but it stalled once - would turn over but wouldn't start. Finally, after getting pissed off and kicking the kick panel (that is what the name means, right?) it started. I didn't really think this fixed it - but it got me started. It happened again on the express way. Had the truck towed - got home - it started. It ran for 15 minutes and stalled. WTF?? Replaced the ECM - nothing changed. The guess was I was loosing power to the fuel pump. Since then - I haven't had an issue.

I don't know if this is the problem or not - but might be something to check. I don't really see how an EGR could cause a truck not to start since people have completely removed them without issue - but stranger things have happened.

This is very strange cause when the engine dies, it will crank fine but will not start unless I pull and reinstall both ECM fuses then starts right up. It happened twice and it's real bad when this happens in traffic. Other wise the Ty runs great and just started to happen the day after the check engine light came on and set a code 32 EGR. First time in 8-years for something like this.

Thanks for any ideas,

The "kick panel" thing is one I aint heard of yet.. Yeesh, something else to look foreward to happening.

Anyway, the code for the EGR may be a clue. If the EGR selonoid is hosed and letting full vacuum to the EGR valve at idle/light throttle then the eng can very easily stall. You can test this yourself by using your fingers to compress the EGR diaphram while the eng is idling. It will stumble slightly and die quickly.

It may also be the EGR itself or the controlling ckt for the EGR selonoid (ECM/wiring).

The only other clue I can think of right off is like what Dave spoke about. If the eng dies just like you turned the ign off then it may very well be something like he ran into. If the eng stumbles very slightly before dieing then you may check the EGR system out.

HTH or at least gives you something to check out.

I just went and checked the EGR by pulling off the vacuum line and holding my finger under the port while the engine was running and pushed in on the diaphram of the EGR and engine did not stall or change RPM's. So does this mean the EGR valve is stuck open? I also diconnected the vacuum line going to the EGR selonoid and sucked on it and I could see the diaphram moving but was wondering if the actual mechanism could be stuck open.

Thanks guys,

Block the lines going to the EVRV (EGR valve controller, on driver's side near the coil), see if this helps. This might eliminate possible vacuum issues.

Also, pull the EGR valve and see if the valve is stuck open, check the EGR gasket also. The EGR valve is a common part, should be easy to get at Autozone/PepBoys if it is dead.

I'd watch the truck on a scan tool to see what it's doing when it dies.

Just picked a Boge Warner EGR up at Pep Boys which looks alittle different but the GM part number crossed referenced. It doesn't have the diaphram exposed like the stock. I'll hook it up and see what happens. Also the old EGR gasket is only a couple of months old when installing my polished upper intake. It has to be stuck open.
Also alittle hard to start reading data master when the Ty dies at a intersection when you have a dozen people behind you beeping their horns in rush hour.

Thanks guys,

Well got stranded today but luckily it was by my sister house and it started up 3-times after 20 min. of trying but would die as though someone just unplugged something. Had it towed home on a flat bed. Changed out the EGR yesterday and the old one wasn't stuck open and seemed to be fine. Battery cranks good, alternator replaced a month ago, batt. cables tight and clean.
Another strange thing which just started to happen a couple of weeks ago was when trying to start sometime, when you turn the key nothing. Similar to before I installed the hot shot relay 3-years ago. Other times it just cranks but won't start. Pulling the ECM 1 fuse and reinstalling which worked the past 3-days doesn't work to start anymore.

Any suggestions would really be appreciated,

After reading throught the Sy/Ty archives and GN archives comparing my symptoms, does anyone think it might be the ignition module,coil or oil press. switch? Checked fuel press. again at it is holding steady. Going to try and see if I can get it started long enough to get a reading on data master.
Also noticed that my stock oil press. is around half way on the gauge but noticed it drop to just above quarter after running the past couple of days. I'm not sure if it always did this but thought it use to stay around the half way mark.

Thank You,

List members,

I finally was able to get the Ty started after 15-min. or so and got data master to record while idleing. If anyone would like to take a look and give me their opinion, I would appreciate it. It stayed started for around 4-min. and then cut off again and I couldn't restart.

Much appreciated,

:cry:

Rick,

I think I have an extra ignition module at home if you want to try it. I will check tonight and bring it downtown tomorrow if I have it.

Dave,

Thanks for the offer but just had the Ty towed into this 4x4 shop near me. The guy does work for me occasionally and I just don't want to start changing out parts that don't need to be. I'll let you know the outcome. BTW, it started up twice this morning with no problem but data master showed the volts were only 10.5.

Later,

Well the shop called and said that my iginition module was bad which toasted the coil. I was ready to changed these out today if the shop was busy but they saved me some time and agravation especially with the little screws holding the module in the distributor..

Also gave him a ES trans mount, greasable spicer joints for the prop shaft and a new U joint for the driveshaft to install for alittle preventative maintenance.

Re: Engine Died

Haha. I actually remember this situation back in the day with my Dad. The Ty sure hasn't given us much issues in the 23 years of ownership. Thanks for bringing this back up Rob nice to read the old posts.

Re: Engine Died

In all sincerity Rob, Sean has done a wonderful job with the Typhoon since he has owned it and I also wanted to thank you for all your time over the past years to help mentor him in the tuning aspect. Sean also did alot of reading on this site and I also wanted to thank the many members with some valuable info you gave him over the years.

I remember several years ago Michael Hood suggested to Sean to get Code 59 and he was real nervous. You gave him the confidence and taught him all the parameters where he is now confident with tuning. You gave him a solid tuning foundation that he will carry with him for ever. Now when he goes to Holley system, he will be familiar with whats going on.

To you Rob and all the other members, You Guys Rock!;)
