1994 Buick Roadmaster V8 185000 miles
My car I just put a starter, fuel pump, a full tune- up, and computer on it! Now when I drive the it's fine until I cut the car off. If I try and turn the car back on it will not unless I wait for maybe two hours or so.
When the problem occurs, if your saying, it cranks good but won't start? Have a helper crank it while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. If there is a problem with wiring circuit, somewhere, replacing parts won't fix it. Are there any applicable trouble codes?
