I was driving yesterday doing 80ish and around 3000 rpm the car made a popping sound and then died. got it home and the car cranks but wont start. I have spark, fuel, valve train movement, and as best i can test and tell i have compression. any ideas on what could have killed it?
cranking but no start
- Thread starter ravenmetals
- Start date
first what kinda car is it and how many miles do u have on it I just got done with an older dodge truck that acted like the timing chain went out.spit and sputtered but wouldnt run.So i Did a tune up and put new chain in still no start. Came to find out the cat was plugged cut it off and it runs like a million bucks
Try doing a compression test. If you find all cylinders are low, the timing chain probably jumped.

daughter's pontiac bonneville coughed once and backfired in our driveway. cranked but no fire. checked spark, fuel, vavletrain movement, ect., all were there. had me scratching my head. went to work and talked to one of the techs. he asked if it was a 3800 early style? i said yes. he said to replace the timing chain and gears and pull the oil pan and clean everything out of the pan. he was right. nylon gears were everywhere. put steel in with new cam button and new gaskets. just like new....
What does the spark look like it may not have enough juice to fire it up. I know it's back in the dinosaur age but my dads Z/28 had the same problem, come to find out it was his condensor in the dizzy that went for a crap. just a thought.
Yes, a bad condenser would cause a no-start situation. I remember at work, when I was in High School, we had a bad condenser on the wall labeled "The $200 Condenser". It had people baffled as to what was the problem for quite some time. After $200 of shop time, the problem was found.
I assumed that ravenmetals had HEI, but it may be a bad assumption.
