my 88 cranks but doesnt start
:?: hi this is my first post and first visit to this site... i think its cool... anyways my 88 bonneville 3.8 v6 with 72,000 original miles took a dump on me the other day. its cranking but not starting and every so often will backfire out of th air intake with a pssshhhh sound. im guessing its an electrical problem like a bad sensor or something. im getting fuel and spark, but the spark seems weak. the car ran just fine prior to this with the exception of stalling twice in the last 6 months... any suggestions would be greatly appreciated.

You mention having spark and fuel. Can you tell us how you determined those.
If possible fuel pressure reading.
May be crank position sensor since that is what tells the coils when to fire.
