The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

Crank sensor has to be bad,or the ignition module.Remove the ignition module and have it checked at the parts store.If it checks bad,replace it,if it checks good replace the cranksensor.The cam sensor,cranksesor,and the control module control injector pulse,and coil spark.I would point more to the ignition module.But I have known the crankshaft sensor to do this also.I hope this was helpful,if so,let us know,thanks,and good luck.

The best thing would be if you had a scan tool to monitor the o2 sensor.If you suspect water just add some Heet in the tank and see how that goes.The only other thing is to check fuel pressure but the tester that hooks up on these is one that has to be hooked up on the fuel lines between the filter and the fuel line that goes to the pump.The fuel pump is in the fuel tank.There could be problems there also.The rubber fuel line from the pump to the sender could be bad or deteriorated.There is also a pulsator that is between the pump and the sending unit that can be bad. You could also have a plugged fuel filter.Depends on if it has ever been changed or not.Hope this helps.Good luck.

Testimonial: "Yes, I changed the fuel filter and have run Heet and other additives through the tank. I'm thinking fuel pump is the problem. Thank you."

Coils and wires are the most likely culprits as they never get replaced hardly ever. You cant really test a coil, you can check for resistance on the plug wires but that doesnt tell you if the insulation is bad on them.

If you hear any noises from a fuel pump that's probably not a good sign, but I'd suggest checking your starter if the car wont turn over. If you think fuel is the problem check for any leaks that are visible, it could be a vacuum leak but I doubt that because that wouldn't prevent the car from starting.

If the engine is turning, but slow, she may need the battery terminals cleaned, if it has sat for over a year, yes, it may need a new battery. If the engine is turning over and she is not cranking up. Standard rules apply... does she have fuel? does she have spark, does she have compression? First thing is easy, get a can of starting fluid and give her a spray in the air filter area during cranking, if she pops off you have spark, which means no fuel. If it does not try to hit, that means no spark and more trouble shooting will need to be done. If it starts on starting fluid, you may have a bad fuel pump. AS gas turns to gunk as it dries up. And that may have gummed up the pump and filter. Hope this helps FixYa up.

I put in another engine on my Toyota Tercel but it wouldn't started if I put gas in the carb it turn and run for a little while then turn of help I believe it the fuel pump.


Your right, it's the fuel pump. It's not pumping gas into your carb. Hope this helps, James Booth. Also, check the fuel pump fuse before you go into all that work and money to see if its no good. PLEASE RATE THIS!! :))

Could be the fuel pump. Try hitting the bottom of the fuel tank a few times while someone try's to start it, if it starts then the pump is on it's way out.
