When the last time you did a tune up on it, it might need the spark plug and filter replaced.

When it fails, check to see if you still have spark. Could be bad coil.

HI! The other thing that controls the fuel is the PCM (powertrain control module). The PCM is like the car's brain that when it fails everything else's fail. The PCM has connectivity on all electrical current that runs inside the car including the engine and transmission. Hope this helps and thank you for using FixYa!

Sounds to me like the fuel pump is worn out. They DO wear out. And even though they seem to be working, the brushes in the electric fuel pump may not be contacting all the commutator, thus making the pump weak. It may start the motor but can't maintain normal running pressure (27-35psi). Have you run the car out of gas shortly before this problem surfaced? If you have then it's your fuel pump. It was damaged when the tank ran dry. Even though the pump may seem to be working, it's still badly damaged and needs to be replaced.
Just as Matmenzies has stated, get a fuel pressure gauge and test the pressure. I'd start with a complete check of all your vacuum lines. Check for cracks on the vacuum hose that connects to fuel pressure regulator on the fuel rail. Also, if you can, get a hand operated vacuum pump to check the regulator. If you can place a vacuum on the regulator and it holds, I'd say move on the fuel pump and check it.
BTW, if the fuel filter has been changed, you may want to check to see if it was installed backwards! Some fuel filters are valved and will cause symptoms like this. However, this is an immediately noticeable mistake and you haven't provided enough info for me to say more. I'd pull it and check that it has any flow at all. You could have sucked in a big dirt ball and blown it right into the new filter, effectively stopping fuel flow. Then I'd blow out the fuel lines, just to be sure.
Start with these 2 things and post what you find. We'll go from there.

I'm willing to bet you have bad fuel injectors. Back in 91 they had a problem with on injector shorting out causing the rest to short out. I have a 91 that had the same problem, and my injectors were junk.

It can be low fuel pressure or clogged fuel filter or issue with IAC valve.

91 toyota pickup wont start


Thanks for choosing FixYa. Sounds like your fuel pump Nathan. Sounds like it is close to failing. You need to make sure your fuel pump is getting 12V of power or close to that. You could have an power issue. If it is not getting the full amount of power, it can do things like this. If power is good, it is probably the fuel pump going bad.

My 1991 4cyl toyota pickup died while idleing. What are some suggestions on things to look at?


A diagnostic scan is always a good place to start, even if there is no check engine light on. Ignition...are you getting fire to the spark plugs? Fuel pressure, fuel pump, clogged fuel filter, air filter not restricted? Battery fully charged, terminals clean and tight? These are a few basics needed for proper engine mangement.
Good luck...hope this helps...please rate me a fixya.

94 yota pickup starts and idles breifly then dies


If it's not your fuel filter plugged , or fuel pump malfunction, then it is probably your Mass air flow sensor, or your coil pack etc. You'll have to see if you have spark or fuel first. One of them is missing.

2001 cavalier barely starts,sometimes runs for a few seconds, then dies. i already changed fuel filter,pump relay, new plugs also. i can hear fuel pump come on for a few seconds,when turning on the key....


Three things.
First, you need to check the MAF sensor for contamination.

Second, check fuel pressure, if you dont have a gauge, autozone and Advance have them on their tool loaner program.
Should see 35-40 psi with key on engine off, cycle key a few times, if it takes a while to build up, replace filter and retest.

Third, possible convertor blockage, easiest check is to remove the 02 sensor and try to start with the hole open, if it runs, then that is it, specs allow for 2-3 lbs of back pressure max. That means if you can hear pressure escaping, it is a problem area.
