When hot will randomly not start unless gas pedal is pressed all the way down. on a 2001 honda crv. replaced fule pump,fuel relay,fuel filter, dist. cap, rotor, coil,plugs, wires, and ignition control


If you hold the pedal to the floor it puts the fuel system into Clear Flood Mode. This prevents the injectors from firing and lets the already present fuel burn out. Now if this has to be done on every short trip you probably have a leaking injector.

Does the vehicle seem to crank slowly or stop and then crank when this happens?

93 Plymouth voyager will start but stops right away


Could be a long list of things, starting with the shutdown relay.
This relay powers the coil, injectors, and computer.
You would need to put a meter on the coil or the injectors and watch to see if power is lost when the engine dies.

I have a 1987 Ford Tempo. The car has a hard time starting. When I get it start it won't Idle. You have to hold the gas pedal down and even then the car wants to surge. What do you think the problem...


This may be as simple as a bad idle air control valve which controls the idle , it may also be a weak fuelpump, i would first have the fuel pressure tested to make sure its good, then i would clean the throtlebody with cleaner and replace the idle air valve. the engine it must not be skipping due to a sparkplug or sparkplug wire, there are many things that will cause this. you will neeed to do some checking and make sure the engine is operating good, is you have a bad idle air control valve you should be able to hold the gas pedal a little and keep the engine running after a few minutes the engine should run okay with you holding the pedal , keep in mind this is a 1987 tempo i dont know how many miles are it or if the engine is in need of work but if this is whats happening then try cleaning the throtle and replacing the iac valve. good day.

Ever since i ran my isusu rodeo out of gas, it will crank but it does not want to crank. I've add additives to clean the injectors, i've changed the EGR sensor, with very little help. cld u give...


maybe it didnt run out of gas but just shut down, if it did run out it may have sucked up dirt from the botoom of the tank causing the fuelpump to lock up, what you can try to see if the pump starts again is to spray starting fluid into throtle body and cranking the engine, the engine should start and will die out after fluid is burnt but may stay running if power stays to pump and it frees up, you may have to try this a few times, if you spray and it doesnt start then you may have a diffrent problem. make sure to have someone hold pedal to floor and spray for 3sec, then release gas pedal connect hose to throtlebody and try to start. good day.

2000 jeep cherokee sport 4.0 dies want idle


This has happened all of a sudden?
It is sounding like it is starving for fuel...

First we will check for bad fuel. A GOOD Gasline Antifreeze can get the impurities and water out of the Gas. Get a bottle and pour the whole thing in the gas tank, bounce the car around to mix it with the fuel. Start it and let it run for a little while so see if it smooths out. If does not help then look at replacing the fuel filter as it may be clogged.

Motor bogs down at stoplight when pushin gas pedal


The fuel pump relay will cause a stalling or no start condition. You are likely having mass airflow sensor, fuel pump, or fuel pressure regulator issues.
