I have new distributor can sensor and cap, new spark plugs new wires . New crankshaft sensor o2 sensor 3 sensors on the throttle bodie. Gas pressure is 40 psi fuel injectors all spit fuel. Got spark got air won’t start drove to work went to parts store wouldn’t start still hasn’t I’m at a loss not understanding what’s going on fuel pump kicks on starter good battery good alternator good what is going on. Any idea please help don’t understand what it is as I u destined it can’t be the computer.

 

I'm confused. You "drove to work" and parts store?

Now try and be more descriptive.

Does it not crank at all? Does it crank weakly but won't start? Does it crank strongly but not start.

Was it doing this "before" you threw all those parts at it?

I see it's a '97, what codes are you getting?

Check your battery cables and connections (both ends).

 

So it’s cranking but not even a try to start at all literally just cranks over with not even a lil start up backfires same issue before I threw parts at it would not start then while I drove my rpms would drop to the floor let off gas gas go again drove then conpmetly went out and wouldn’t start at all. I had it running the other day drove to work about 30 min got off work started right up went to the parts store 5 mins away can back out to start nothing won’t start since then

 

 

Other than the parts cannon issue ...given the symptoms and the codes I would be looking really hard at the wiring harness and doing all the grounds.

It's pretty obviously an intermittent electrical issue.

 

Ok will do thank you I appreciate it

 

So if you have air, spark and fuel BUT have a P1391 code, the cam sensor is not synched

Have you had the distributor out ??

Verify its rotating when cranking with cap off

As someone else said, could be a wiring issue, do the ground thingy, and check the wires around dizzy and coil, known to be suss

Did it ever work perfect? Give us more clues. DO NOT throw away used OEM sensors
