1993 plymouth laser, 1.8 automatic, FWD. will crank but wont start.
we replaced the plugs, wires, distributor cap.
Any suggestions to solve this problem?
and no i dont want to hear the take it to the junk yard BS. Looking for help to fix as this is a DD. Thank you in advanced.
EDIT: possibly the injectors? fuel is getting to the fuel rail.

You getting spark, fuel, or nothing?
Check fuses?
It’s all rather vague at this point until you post up some more specifics. If there is no spark, and the injectors are not firing then it might be a cam/crank sensor, ECU, or general wiring issue.
Scrap for a better DD.
I keed.

im not 100% sure about the crank, but the cam sensor will play a big roll in not starting either properly or at all, without it working it cant give correct spark, and since its not obdII it sucks that youre not storing codes to help you out, to make sure you have spark take out a plug and put it on the exhaust manifold and see if spark archs across the plug, check the lil valve on the fuel rail to see if it keeps squirtin out fuel, its the least you need to do, anybody can check fuses that helps for shit cause 99% of the time fuses are fine

It generally looks like the valve of a bicycle tire.

The cap doesn’t hold in the fuel pressure, it just protects the valve. And god I hope you haven’t located the a/c valve…

ran, then rpms seemed to decrease from 750 to about 300 then it stalled and after that it did not want to start.

Fuel or ECU problem. Can you smell fuel coming out the exhaust?

If there’s a valve on the fuel rail, try to start the car. Then press the valve like you’re trying to let air out of a tire. Cover the valve with a rag or some paper towels to catch the fuel if it sprays out, it should be pressurized to 40-50psi so it will spray out far. If nothing comes out it could be your fuel pump.

If there is fuel, I’m going to say the ECU is bad. 1st gens are notorious for ECU failure, the capacitors start leaking. Good luck.
