I have a 91 camry cyl 5 spd 83,000, year old plugs, wires, cap and rotor I started my car to defrost the windows and went back in the house. I came back out and it quit running. I tried starting it again and it would try to start but just wouldnt keep running. The gas pedal does nothing to it once it starts to run. Throttle position sensor maybe? Thanks

Let's review.

It started, ran, and quit.

It will start again, and then quit again.

I would begin by pulling codes.

Have you ever changed the fuel filter?

Actully it wants to start sometimes, but sometimes it just cranks and cranks with no hint of starting. And not sure on filter ive only owned it a year. I just parked it last night and didnt have any problems with it since ive owned it. Not sure how to pull codes, but ill try that next. Thanks

try reconnecting the plug going into your AFM, it could have come lose and if there's no connection the engine will start but it won't accelerate and it won't keep running for long, which is what you're describing.

it's the one near your air filter.


Tried that too but no luck, Thanks

Codes:

http://oregonstate.edu/~tongt/camry/

Click on the link for the car (top link)

Scroll down to "EFI"

Scroll to page 23 of the pdf file.

In the same online manual, there is a process for checking fuel pressure. I always check fuel volume as well, looking for a minimum of one pint of fuel pumped in a maximum of 30 seconds.

Do you have a consistent, strong spark?

it could be the igniter. but follow timebuilder's advice. you may as well change the fuel filter and get that out of the way. as for the codes, there should be a diagnostics plug in your engine bay (someone correct me if i'm wrong) between the firewall and the driver's side strut, just at the top right above of where my picture ends.

turn everything off and bridge connectors E1 and T, now jump in the car and turn the ignition on, but do not crank the engine. you should see the engine light flash at various intervals. these are your codes.

If the car still starts sometimes, I'd have doubts about the problem being a bad igniter. Usually they fail 100% and never come back.

Just follow the procedure in the online manual, and for following up on any codes.

Take an old plug and ground the shell of the plug to the engine block while connected to one of the spark plug wires. Have someone crank the motor, and make sure you have a good strong spark.

you would have had a lot of fun with my celica. it is the opposite of everything related to "usually".

my igniter started failing when the engine was warm once or twice a month. eventually it failed altogether, after several months.

Yes, there are always exceptions. My Supra had a few, too. ;)

That said, much of diagnositics is to look for the usual first, and when the usual does not reveal the cause, then shift to the unusual.

In this case, checking and finding a good spark on a car that won't start pretty much would eliminate the igniter as a causal factor.

Put Jumper (paper clip) between B+ and Fp terminals inside the diag. box. Try to start the car after that.If it starts and keeps running, check the items suggested above. If the car does not start, make sure that power is coming to the fuel pump.

Do you have a consistent, strong spark? Also I for got to mention that I think I need a new starter because sometimes I can hear the relay clicking but the starter doesnt turn over. So I have to push in the clutch a couple times before it turns over. This only happened a couple times in the last 2 months, but today its happening every time I try to start it. Could this be a relay issue or just another problem, is there more then 1 circuit runing through the relay?

Ok , I got 2 codes a 12 and a 43. Also when I tried to start it in the last 2 months I could hear the relay click under the dash but no starter action, this only happened about 2 time though. I just thought I needed a starter. But today every time I try to start it it did it so I had to push in the clutch a couple times to get it to turnover. Could both these problems be a relay problem? Is there more then 1 circuit in the starter relay? Also I tried to search for similar posts but it came back with alot of irrelavant posts. Thanks

Good.

I would stop for a minute and determine if you are getting a good strong spark when the engine is failing to start. Use the wire from one cylinder.

Went out this morning and tried to start it just to see and it fired right up, so moved it into the garage so I could work on it where its warm. So it will probably be tougher to troubleshoot if it working.
