I drove my old Silverado 20 miles home and while turning in the driveway it died. I restarted it long enough to back up to the garage, but it would not start after that.
It appeared that we had no fire, so I replaced the coil. It started but died again after driving to the end of the driveway and partway back to the house.
This is on an old Chevy Silverado (1993) w/ 350 engine w/ 190k on it.
Looking for ideas on what to check next.
Unfortunately there's several components that could cause your symptoms, because it started again and I assume ran ok for a bit I don't think it's the cap, but check the center spring loaded nub.
Let's see:: crank sensor, pick-up coil, ignition module, even the ecu (electronic control module) or as Paul said the fuel pump could be shot, it may be pumping just enough to start up sometimes, then gives up. but you said no spark so most likely it's a ignition or a control issue. None of these parts will set off the MIL except the crank sensor under some conditions.
I don't think it's your coil pack, it usually dies outright (wouldn't start at all)
I'm sure I'm missing something, like a bad ground somewhere, even at the ecu? but these parts are common failures.
Do you have a heavy gas smell? You could pull a plug and see if it's damp with gas. I can't remember if this system has a fuel pressure hook up schrader valve, but if it does and with no start you could depress the valve and if only get a little spurt, that would be a fuel delivery indication. (it should have about 40-60 psi) some of the systems need the whole spec pressure 46psi? (if has truely no spark I'd start somewhere else though)
Gotta recheck spark and fuel delivery to isolate control issues.
I'm sorry I can't be more specific help Doc, but with no CEL (MIL) to guide us?
If you can get more info I might be able to be more help.
Good luck............Tim (who does this for a living)
