Is there a fuel pump prime in a 98 corolla , in the acc key pos. my pump that I changed seems only to run when I crank the motor

SOURCE: 2000 toyota corolla ve engine will run at idle but

Install a new mass air flow meter i own this car ive had this issue with my own and several others

This problem does not seem to be the fuel pump. it appears to be an electrical problem in particular your ignition. Also check the MAF (Mass Air Flow) sensor. if the computer cannot read how much air is coming in it will try to shut down.

Yes there is reset procedure:----If its a factory security system its disarmed by unlocking the drivers door with the key. -------------- If its aftermarket (may have been installed at dealership and sold as factory) then you need to look around in the drivers foot well area and locate the valet switch.

The after-market installed alarms have a valet switch to defeat the alarm from being armed on it's own. This switch is usually located on the left kickpanel depending on the installer. The kick panel is the panel next to the left foot, driver's side. -------First disconnect the negative terminal of the battery, wait for 2 minutes.Then before reconnecting the battery, turn the ignition switch on and flip the valet switch in the opposite direction. Then, reconnect the battery. If that doesn't work, redo the same procedure by flipping the valet switch position.If that still doesn't work, cycle the ignition key on and off a couple of times to see if that does anything.-------------But if that is not helping then, the key and alarm has to be reprogrammed by the dealer.In the car there is a computer.This computer is called ECM/ECU( electronic control unit or module) .If the ECM/ECU is not detecting the key or security system, then it will not let the car to start.And this has to be re-programmed by the dealer.----

This should help.Keep updated.Thanks.Helpmech.

A hard-start problem can be caused by MANY things - especially when we are talking a bout a 21-year-old car. Since this problem only occurs on a warm engine it leads me to believe there is a problem with either the engine coolant temperature sensor or the fuel pump switch located in the mass airflow meter.

HOWEVER, The FIRST thing you should do is check to see if there are any fault codes in your computer. This is relatively easy to do. All you have to do is connect a jumper wire between the "E1" and "TE1" terminals in the diagnostic connector under the hood (see picture) and watch the check engine light flash. If there are no codes present, the light will flash continuously and evenly.


A fault code will be identified by a .5 second flash on and off for the first digit in the code, then tere will be a 1.5 second pause and the second digit will be output. If there is more than one code present, there will be a 2.5 second pause after each 2-digit code, then the next code will be output. After a 4.5 second delay, it will begin outputting codes starting with the first code again. (see code example below.) It is recommended that you read the codes several times to make sure you are reading it correctly.

If there are any codes present, this must be dealt with FIRST before any other troubleshooting can be done. If there are no troublecodes present, then a whole LIST of stuff needs to be checked and verified before going out and spending any money on parts.
