My TBI TA started stumbling and acquired a rough idle all of the sudden while drivig it the other day and simply shut off at about 25 MPH...the next day the idle is even worse just sitting in the driveway and stalls in evey gear that it's shifted into...by the third day, it won't start at all....

Ok, so all the plugs and wires look good, I replaced the inline fuel ilter as a first measure but that wasn't it, also, when I turn the key to ACC the fuel pump still energizes and primes like it's supposed to.....what else should I look fo here? What would make it not start at all now? I know the charging system is ok, so that's out. But I guess I could still be in the igntion area even though a visual check looked ok on plugs/wires....any help or suggestions are greatly appreciated. Thanks.

 

we need more info...is it getting fuel? take off the intake and see if the injectors are firing...is it cranking? is it for sure getting spark? pull the coil wire off and crank it and see if it arcs...sounds like a coil or maybe a ignition module (checked for free at parts stores) or the pickup coil in the distributer...check for fuel and spark and get back to us

 

Yes, it is cranking, it's definitely getting fuel, and will just not fire up. What do I do to check the coil wire t get it to arc? Pull one side and try to start the car? Thanks.

 

What's your fuel pressure look like? It sounds a lot like when my fuel pump went out. Just a gradual worsening of symptoms with lots of stalling. It still primed and sounded healthy and everything, just wasn't doing it's job.

 

i would check your pickup coil in the distributor, a good check is to hook a timing light, if it blinks it somthing else spark related, if you get no flickring light, you pick up coil is shot, and its like a $8 part

Are you SURE it's getting enough fuel? Like JZA said, it sounds like a fuel delivery problem and more likely than not a bad pump. The car will stall when it isn't getting enough fuel and it'll just run like crap from being lean.
Maybe fill up the gas tank with some of that stuff we call fuel , just kidding but you'd be suprised...

 

What should the fuel pressure be on a TBI car? Thanks.

 

Raptor,

Please check your email. I'm still waiting for a response on the plenum.

Thanks.

 

id check the coil and pickup first sounds like thats the problem may be the fuel pump but you dont want to change that unless you have to for sure its rough :lala:
