I have a 1999 dodge intrepid 2.7L that has no spark. Here's my long story.
I bought the car and the next day i drove it and the engine blew up, so I found a used engine and put that one in. I followed the instructions on the Haynes manual on how to put the engine in because when I picked up the engine I couldnt get a hold of a truck so I had to disassemble it and put it in the trunk of my car. I am positive I put everything back together good except for the timing. What I think is that maybe I didnt put the correct timing and thats maybe whats causing the "no spark" problem im having. But then, when I found out that I had no spark, I found a mechanic and all he did was jiggle the camshaft sensor then push it in and I cranked it and it started. The thing is that when it did start, it didnt sound good so it was only on for about 15 seconds. it sounded like it was the valves making the tapping noise or something like that. I know it wasnt the piston hitting the valves because the noise wasnt very loud. So then the mechanic suggested it was either the crank or cam sensor. Well, I changed both of them and still no spark. the ignition coils
are fine and the spark plugs are fine aswell. I checked the ASD relay and anything in conjuction with the "no spark" and it all turned out ok. The battery
is new. One thing I noticed, is that after that time I turned the engine off, a couple of days went by and then the oil light came on. So I checked the oil pressure sending unit and since it was only 5$ I changed it and now it remains on. All the fluids are at their proper level.
So my questions are.
1) could the PCM be out?
2) should I have the timing checked?
3) can an alternator
cause a "no spark" problem.
4) why is the oil light on?
5) what is the most probable cause of the no spark problem?
I would greatly appreciate help with this.
