Any one have any ideas
No start conditions on a 91 s10 blazer it's a 4.3 4x4 automatic trans and I was driving down the freeway and it shut off on me I got it towed home and it was flooded in the throttle body i got a new fuel pressure regulator and it still won't start and doesn't seem to be flooding anymore but still won't start
I just got new plugs and some carb cleaner for my injectors but and I'll get a tbi rebuild kit but other than that any idea?? |
Ignition module or the coil would be my guess.
Check for presence of spark. Best done with a spark tester which plugs in between the plug and the spark plug cable. |
I'll test them after work today but the icm is new replaced it with the distributor and the coil is new too I'm thinking it could be a plug
|
Well my icm and coil are about 4 months old I popped the distributor cap (I just replaced the whole distributor about 4 months ago with cap and icm all one part from O'Reilly's) off and the terminals were alittle black I cleaned them and they look like new and I popped my spark plugs out and all of them were wet with gas and my tbi isn't flooding anymore I replaced the fuel pressure regulator and I walked up to the parts store and got some new spark plugs and wires and I have a cracked plug on the coil and I ordered a new one so I'll splice that in tomorrow and put it back together and see if it will start ( I also replaced my oil pressure sensor and sending unit a few months ago but the gauge still turns off and on when my truck is pretty hot and it's warm out..)

I'd suggest at this point to check the whole electrical engine wiring as far as you can.
Look for broken/rubbed insulation, funny repairs, anything that could cause a short. Then, even as it is a remote possibility, I would check ignition timing to be correct. Not the first time a loose distributor decided to turn a couple degrees. |
Ok where do I start on this 28 year old thing it definitely has funny repairs and sketchy looking black electrical tape and there was a fire in it over the break booster at some point and some wires are spliced back together with just white wire... If I can figure out how to post pictures I'll try but yea any advice is much appreciated it's my daily and I'm young and work full-time and don't have anyone to really help me out with it so anything to make my life easier is awesome thanks in advance for the advice

Uh, oh! That looks bad. Definitively to check the whole of the wiring in the engine bay. Even corroded connections from the wrong input to the ECM will make it no-start or no-run.
|
I'm crying for you my friend... that's a mess I would not want to deal with! Maybe see about a replacement from a wreckers?
|
I wasn't getting spark from the coil I replaced that and it started but it's smoking like a chimney and my injectors are wet on top I guess tbi rebuild and maybe new injectors if I can any other ideas guys..
