Ideas?? No start, not fuel, no spark, no codes

[DanenGraham]

I am open to any an all ideas you guys have so let me know if im having a brain fart. And it gets better. (garage got broken into a while back) I have been pulling the ECMb fuse and unhooking the inj harness to make sure people didnt drive off with it. This is why am thinking its something ease that i am overlooking.

Truck ran 2 months ago and was low on fuel.
Tonight i put 5gal fuel in and heat
I am getting about 30psi fuel on the prime.
Put new fuses in both ECM slots 10amp
Injector harness is pluged back in

Plugs were dry, and i wasnt getting spark to the dist.
It is not throwing any codes at this time

Is there a fuel cutoff switch anywhere on the truck. I have had the bed on and off a lot, as well as stepping all over the fuel tank. So is there anything by the tank that would do this??

And will a 225amp starter box fry a ECM??

Thanks for the link. Just went back and jacked with it some more. Its so cold out in the garge. Im bringing it back to my house tomorrow morning.

FPump is hard to hear, it is priming and it sounds like it is staying on while cranking. but its so hard to tell with the dump open. Have that at my house. fuel pressure stayed around 30psi

I still have no spark, distributor is down/tight, coil looks like.... a coil. Need to test the coil and take the cap off and check the rotor. And the spark plugs dont even smell like fuel

Lucky i still have spare ign mod, coil, and dist.

Damn, might get it painted, if it would run. Figures, it sits and starts fine for 2 years and now it takes a shit. And i may have done this myself, havent ruled that out yet.

Stock everything. Its all been replaced before though. And again thanks for the help

The stock Oil pressure sending unit is gone, and the plug is just laying on top of the trany

With regards to checking the coil, here's how you do it if you have an ohm meter:


"This is a brand new MSD coil #8226. The coil does NOT have to be removed from the vehicle to perform these checks. Any connections on the terminals will have to be done with a paperclip or other small object as the test leads won't be able to reach the pins inside. This value should be infinite resistance (open). If not, replace the coil."


"From here on out, the resistive values are not "carved in stone" and are approximate. Here, the value should be very low or zero. If not, replace the coil."


"Here, the resistance should be high but, not infinity (open). If not, replace the coil. *These checks will work on a stock coil as well*"

I wish that I had Dave's luck with ignition modules in my GM vehicles. I have had to replace it in every one that I have ever owned :


"If the chip is installed correctly, and you definitely have both spark and fuel pressure, your ignition module is dead. A bad ignition module won't generate a reference pulse preventing the injectors from firing. Part number is 1048-2827 (located under your distributor cap, BTW). Some auto chain stores can test to confirm it it's good or bad"

Thanks for the how to no the coil, i have done it before but its been a while. Im hoping its just the ign mod.
