Thank you for that information. If you disable the fuel pump, does the engine start and run on starting fluid?

Customer: replied 8 months ago.
No tried that no difference
Expert:  AMEDEE replied 8 months ago.

Ok, then the ignition timing or valve timing is off. Have you checked engine compression?

Customer: replied 8 months ago.
it has good compression on all cylinders car supposedly has only 24k miles on it
Expert:  AMEDEE replied 8 months ago.

What are the readings?

Excellent! Was the crank sensor replaced or was the crank sensor signal checked?

Customer: replied 8 months ago.
it has crank signal my older scanner reads 15rpm for some reason without cranking but reads signal just fine
Expert:  AMEDEE replied 8 months ago.

Ok and was the distributor replaced?

Customer: replied 8 months ago.
No not yet since before I toss more money at it and it sits behind the water pump I want to try to pinpoint it first that is why i am talking with you sir.
Expert:  AMEDEE replied 8 months ago.

Got it! Well, based on what your telling me, I suspect the problem is going to be a bad distributor and or a bad distributor cap. These are the only things left in the ignition system that would prevent the spark from timing incorrectly.

Customer: replied 8 months ago.
If you believe that is the problem I will replace it. Could you tell me why would I have heat in the header pipes if it's not firing correctly and you don't think it could be a computer issue or a wiring problem
Expert:  AMEDEE replied 8 months ago.

Excessive heat in the headers or exhaust is because it is firing at the wrong time. While a wiring issue or a computer issue can cause this, it would not be very likley.

Customer: replied 8 months ago.
Ok well I hope this fixes it since it will not be cheap is there any other possibilities?? And if it doesn't work can I still contact you ?? Since it will be day or two to get it done
Expert:  AMEDEE replied 8 months ago.

Based on what your telling me, no there is no simple fix. YES, you can contact me in the future if you have any further questions.
