i just bout a 92 sonoma gt with 83k. the guy says it will run for a few weeks and then die and not start for a few days then it will run for a week or so and happen again. he said he narrowed it down to an ignition problem. said its loosing spark between the coil and plugs. he replaced the pick up coil in the distributor and it fired up and ran for a week or so then it died again. i havent had a chance to investigate the problem yet, but i was wondering if anyone has ran into this problem before? thanks in advance

Re: ignition problem...
That is an interesting comment. How does he know this? I think what he means the coil stops firing. Don't know how a '92 Sonoma is wired but (ASSUMING it's like a Syclone) I'd check the connector between the dist and coil. Also a bad or loose terminal within the individual Weatherpac connectors. Another thought. It's not the parts mentioned by you at all. It's the key/ignition switch. Bad/corroded switch can cause all kinds of issues. One last question. When it quits running does anything else happen? Like does the radio stay on?

Re: ignition problem...
im not sure if it is an ignition problem. he just barley dropped the truck off to me last night so i havent even had a chance to really take a look at it. he told me when it dies everything stays on, radio gauge lights ect... he said he recently replaced the fuel pump because it went out, only had 6psi. he says when it happends the wires to the coil still have power but its loosing spark from the distributor. said he replaced the distributor with and OEM one. but like i say i havent had a chance to check it out myself so it is very possible that he did over look something. i was just curious if someone has ran into a simalar concern. im going to dig into it tonight and see what i can come up with. thankis for the suggestions/ help

Re: ignition problem...
so i got to dig into my truck this after noon, was going to check spark, removed #1 plug wire from plug, and the little clamp that snaps on the plug stayed on the plug, so i replaced the wire, spark is good, checked power to pump, getting battery voltage to pump but pump not kicking on, removed pump and checked resistence on wire to pump, ground had 13k ohms between pump and ground wire bolted to frame. ended up finding the 4 pin connector on the under side of the sending unit corroded, i think this was his problem all along. i cleaned terminals and went ahead and replaced pump since its been sitting in bad gas for about a year. now it has pressure but still wont run on gas but will run for a sec. on brake claener. so im thinking the injector might be gummed up. so ima swap it out and see what happens tomarow.

Re: ignition problem...
calm down there buddy, the pump wasnt coming on in the first place but i fixed that now i am getting fuel to the rail, you are right i havent verified pressure yet because my gauge was at work and after working a 10 hour day then working 5 more hours on my sonoma i figured it would be a good stopping place. why would i go spend $285 when i have a spare injector in great working order. im most likely going to end up doing the marine intake conversion on it anyways further down the road so i can run my turbo.
if the injector isnt working its only going to run on brake cleaner untill it burns it all up.

Re: ignition problem...
got my truck running about 1am this morning, checked fuel pressure after replacing the fuel pump and was only getting 15psi, checked lines for restrictions and found none. ended up the idiots at the parts store gave me a fuel pump for a TBI engine instead of the CPI, changed the pump out again, truck fired up and ran great, took off down the road and truck died. found the grey connector on the coil unpluged because it will not clip on the coil, so im hoping thats been the guys problem all along with loosing spark

Re: ignition problem...
no offense, but i dont owe you anything, but i do thank you and the others for yalls help and input, it is very much appriciated.
now its time to start collecting the rest of the parts to convert it over for the turbo set
