Hi,

I have 1995 toyota camry with mileage of 105k has serious ignition problem.I have been struggling with this problem evn till date evn after changing the distributor.
I got it checked from toyota service station but still this problem is persisted with stalling it stops somehwere then it carnks and takes some time to start after anew distributor as well.
My guess is something or the other is causing aproblem in the ditrbutor as well. This is the third distrbutor I got it changed.

But still we are not able to trace the problem.
Could you please give me your expert comments on that as what could be the actual cause of this problem besides distributor.

i will wait for your reply.
Thanks
Saurabh

Sir or Madam

What you need to do is look for an ignition spark at the sparkplug wires while engine is being crank over.

The problem with ignition spark is, if the computer don't get an Ne and G signals it will not issue an Igt signal to the ignitor, therefore no spark will occur-again the computer didn't get an Igf signal meaning no spark confirmation.

Have you checked the EFI relay, Ignition and EFI fuses.

What did the dealer has to say with this problem

Hi.

I have 1995 Toyota camry that had rigorous stalling problem and ignition. This problem is still persisted until now even after changing the distributor and EFI relay.I really dont know whts the problem I got it checked from tire plus they even are more sckeptical now as they themselve are not sure about the actual cause of this.
This had hot starting problem ever since I got this and I had got this checked from lot of service station but still I am not convinced about the actual problem.

I would appreciate and wait for your expert comments and help me to give me an insight on this problem and help me to get rid of this situation.

Thanks

Okay here we go again,

Answer all the Q's
1. Has anyone mentioned anything about the EGR or test it.

2. What did they think! That might be causing the
problem?

3. Did they do a fuel pressure test

From the EFI relay it powers the COR ( circuit opening relay ) from there it will power the MAF sensor ( MassAirFlow ) then it powers up the fuel pump thru circuit Fc on the COR.

Try having them test the COR/MAF and comeback

In the engine compartment there's a diagnostic connector near the fender where they plug in for diagnostics, open it up and locate the batt. And Fp pin jump this with a small jumper wire, now go an attempt to start vehicle and observe its behavior.

Hi.

Thanks for all your valuable inputs and after still struggling with stalling problems and bad ignition I got I checked finally with toyota dealer directly.

They are saying that 1995 toyota camry needs factory distributor, plugs and plug wires. This car cannot run with any other distributor that I had been doing it currently. Now I have life time warranty with auto zone from where I bought this distributor and there is ahuge price difference compared to the toyota distrbutor.

Let me know if this is true or not becoz going with toyota distributor would cost me hell lot of money and I have been spending lot of money in diagnosis and I have changed EFI relay also to make sure that it is abosutely fine.

Please advise me what should I do.

Thanks
