here is some background on my car.
1987 NA 5 speed. Bone stock.
This car ran poorly even since i bought it, but didn't care because i was gonna fix it with all the parts i have.
Now i have given up and im trying to sell it.
I went out to start it today, and it will not start.
Here is what i have done.
-It has fuel and spark
-checked the plugs, they are ok, a little wet and good spark
-ran the codes, everything appears ok(maybe it's because i checked while the engine was cold)
-checked all fuses and fusable links
-i see an rpm signal when cranking
-Battery is good + i kept it on the charger to make sure it was full of power.
-Tried adjusting the timing on the distributor(also tried my spare distributor)
-all injectors are firing
-fuel pump primes and comes on, but i have no way of checking the fuel pressure
Before i had this problem, the car started fine everytime, but it sputtered lots( like a miss) and it backfired alot when you revved it up.
Any input is greatly appreciated, it was running a few days ago and now nothing, just cranks over and smells like gas.

Re: Car won't start!
Mine used to do something like this before, it wouldn't start so I would crank it with the fuel pump disconnected for a few seconds, give it fuel back, and it would usually start. Check all sensors for connection and functionality if you can. Also give the MAF a look.

Re: Car won't start!
I did check all the major sensors and connectors, i also checked the maf, it seemed fine, not clogged or anything, looks like it was replaced a while ago.

Re: Car won't start!
Try new spark plugs!!!
Same issue years ago put it on the scanner nothing… new plugs ran great.
My 2 cents.

Re: Car won't start!
New plugs, still nothing.
i tested the fuel pressure today, i put a gauge right after the fuel filter and it i got roughly 90LBS. does this sound right?
should i put the gauge after the FPR?
also, i used the car on friday to boost my truck, could something have happened?

Re: Car won't start!
I checked for spark at each spark plug, and all of a sudden the car runs like new.
Starts perfect, runs really good, but it backfires under load.
I don't know what happened, but it runs.
