Dear Richard… I had a friend to "just happened" to be in a junk yard on Sunday I picked up an instrument cluster for a 94 Nissan ( I have a 91). After a careful dissection all the way down to the temperature gauge, I did an R & R with the gauge from the 94, and with baited breath, started it up. IT ALL WORKS!–THE THERMOSTAT OPENS AT AROUND 85C, THE COOLING FAN COMES ON, AND THE TEMPERATURE GAUGE WORKS!!!! I would be in a quandary now otherwise–There were so many puzzling things about the car (wrong wire colors, no electrical continuity where there should be, etc.) So this is a very happy ending to a long journey.
Thanks for all your help!

Thanks for the help Rich!
Finally a success!!! A wire was loose at the EEC relay and the relay itself was bad. Your detailed wiring diagram and assistance really works! Thanks,

Hello Rich…
It is now Dec. 20.07 and I am happy to report that we have solved the problem. Following our last e-mail, I took your advice and drove for a couple days with a fuel pressure gauge in the window of the vehicle. Whenever the problem showed up, it seemed there was a temporary interruption in fuel pressure, and the pressure would drop below 60 psi to about 56 or 57 psi, and then it would recover. Still believing deep down we were dealing with a fuel problem, we changed the fuel pump, and found a badly clogged intake screen on the old pump. The clog appeared to be sand, dirt, sludge, corruption!. At any rate the truck is running very well now and has been for 200 + kilometers. Success!!
Thank you for your attention and help, and we will talk to you next time.

RICHARD…you should have been here to see the smile on the wife’s face when for the first time in months; she could signal when turning!
The A/C lower fan speeds are working again! We no longer have to use a pencil to shift the console transmission lever out of park! The anti-lock brakes aren’t pulsating and as a family we fill like we are no longer living in fear that the next intersection will reveal a not so understanding police officer!
A thousand Thankyou’s Richard for nailing the source of this puzzling problem down and pointing me in the right direction as to the successful repair!

It’s fixed!
I have 0.08 volt at the ecm (engine computer) and 1.2 volts at the map sensor terminals and obviously the wire has a short!
I cheated and replaced the wire and now it works fine with no codes with the same voltage end to end! I will chase the harness in the next week or so and find the culprit to prevent further damage to others.
Thanks for your help… Your email and wiring diagram really helped!

I am a happy camper. you sent me down a different path that caused different thinking. and I thank you . Sometimes you just get too focused, and you need to step back and take a different approach. thanks again.

My name is Chris Banks… we are an Auto Electrical and Mechanical repair workshop from Christchurch, New Zealand and we have been using ATS for hard to obtain and sometimes unavailable wiring and technical information in our area.
However with the prompt e-mail service from ATS we can now obtain fast and reliable repair plans and diagnostic solutions, which in return has saved us both time and costs in repairing many different vehicle types of vehicle.
We are now using ATS as a very valuable and reliable source of automotive repair information and would have no hesitation in recommending them to any garage large or small.

Stop Guessing and repair it exactly like how garages do it!
ATS works and SAVED me money…
Hi Rich, I replaced the plugs and the MISS IS GONE! Old plugs look good. This engine was running rough like my corvette which does it when a plug fuel fouls. I almost changed my $300 camshaft actuator but your advice saved me over $200. I could have done this myself but the advice you gave made it quicker for me. I would recommend ATS to my fellow technicians because it’s like having a spare brain in desperate times! The instructions are simple and practical that even ordinary folks can understand.

Dear Internet Friends, I have good news for you! Fixing your car is actually much easier nowadays than what the car dealers make you to believe. Newer vehicles are equipped with sensors, and computers so that at the first sign of trouble, your… Read more…
