    just changed the fuel filter and tested the pressuer and it is week thanks and so now its time to drop the tank and do the fuel pump

  • ryanhempner Jun 01, 2009

    ok got the new fuel pump in and we have the same issue

    lots of fuel pressure but when we start it up we do not see fuel comming out of the injector. but if we put a teaspoon or so amount of gas into the throttle body it will fire up and stay running aslong as you keep a little bit of pressure on the gas if you take the off the gass it will run for awhile but will die and once it dies it will not start again unless you use the teaspoon of gas down the throttlebody

Time to chg. the fuel filter and then do a fuel pressure test, either the filter is pluged up or the fuel pump is weak, my guess is its the fuel pump common problem.

    Rather than drop the tank, i always found it easier to unbolt the bed and have someone help you lift it back about a foot and you can get right at the sender without unhooking anything( but the filler tube,) but its up to you how you do it.

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.

Tank almost empty and husband put diesel in our 2001 rav 4 petrol car. car drove for a little while and has stopped and won't start. what needs to be done to rectify problem. thanks


luckily deisel in a gas engine will not wreck a motor but you have to take the tank off and drain it completely. when full of gas again may burp a bit but in no time purrs like a kitten....luck that wasnt a diesel with getting gas put in it that will wreck a diesel if you start an run it if no start same u can drain it off.flush tank ....but with a gas engine a little diesel will probably black smoke a little but should clean more than harm...thanks for using fixya.

Cleaning throttle plate and MAF sonsor


TO clean the throtle plate use a small tooth brush and some throtle body cleaner. remove the intake hose, spray the throtlebody and then open the throtle plate and spray plate , use brush to clean body and plate then spray clean try not to spray to much into engine , after its clean then start the engine you may have to hold gas pedal down to start as it going to be a little load up with fuel from the cleaner, some time sit will start up on its on and run a little rough for a few seconds and clear up. As far as the mass sensor this needs to be cleaned with mass air flow cleaner, this is a spray like the throtle spray but is made for that sensor and drys fast, spray the two sensors inside but dont touch them or move them spray as close to them as you can to clean them, good luck.

You may have a dirty throtlebody or a bad idle air control valve, start by cleaning throtlebody with an old tooth brush and some cleaner for the throtlebody then if it still stalls replace the idle air control valve. you can also have the computer scanned for codes the computer will store a code when the engine doesnt run wwithin specs, for example there may be a code for the idle air valve. you can go to any auto part store and they will scan the computer at no charge.

Ran it 1.5 hrs idling now chugs at low rpm


This may be due to a dirty throtlebody or bad idle air control valve, using crab cleaner clean the butter fly plate or also called the throtle body plate, spray area and clean with a toothbrush and this cleans it good, make sure to open the plate and clean both sides and housing, when restarting you may need to hold gas pedal down to get it going and clear it out, with thew engine running spray cleaner into the idle valve hole, rais eidle a little and spray a few times, the last thing is if the low idle is due to a misfire like its skipping then you may have a bad wire, (sparkplug wire) but clean throtlebody also, hope this is helpful to you and good luck.
