If you have spark at the right time, compression, and fuel, you should have combustion. Was it running before you had the work done ? Is it possible the distributor timing is off ? You know for sure the plugs are firing, not just the coil ? And the accel pump in the carb is spraying gas ? And the choke is closed ? A major vac leak like the PCV valve hose or intake gasket could keep it from starting.
mine does the same thing, but my security light flashes. I was told that it is the security system on the car not recognizing the key. The key I am using is the original key for the car though. I was told that a quick (but not so quick) fix is to open the door, put the key in, turn it on but don't start it.... set for roughly 10 minutes so the car will reset itself. It works everytime but is a pain in the ****. Was told the only way to completely fix the problem would be to put a new motor in it.
These cars were made with an anti theft security system. If you swapped motors, you may have interupted that system causing the the security to turn off the ijector fuel. Just a thought.
Check for Gas...Check your Timing...You say you rebuit it..was it just the top end, or the whole motor ? I asked, because there is more things to list, but i wont go into too much detail because you might have done most of them anyway..And also check your compression....Goodluck...
Ok since you did all that if you want to swap around fuel injectors taking note where you put cylinder 1 injector. Lets say you swapped it with cylinder 4 . Now if you get a different code say P0304 which is for cylinder 4 misfire then you know it is your injector at fault. These are wear items and should be replaced every 100,000 miles.
Also i would suggest if you dont want to do that is get some good high octane gas when you are completely empty and fill to 1/4 tank now put in Lucas Oil fuel injector cleaner and run the car till empty. Now fill up tank with high octane gas in see if this helps. Clear code after your second tank of gas and see if the code comes back. if code does pop back up then i would do the swapping of injectors as i stated earlier. I hope this helps and good luck with the diagnosis.
With the difference in years, there maybe a difference in alot of things. I'd start with mking sure every sensor, injector, everything links up properly to the 99 caravan pcm. If it's seeing the wrong info it will be a no go. Sounds like it's thinking it's -40 outside(foot to the floor to start) this indicates the coolant temp sensor maybe screwy. Let me know what you find, and about any other changes or issues.
