TPS Testing referring to old post see link

Hello,

See above link for more info..

This is a car I don't get to work on much.... Sorry, for the old post having to referr to it....

The car has NO throttle response at all... Zippo

you press the accelarator and nothing.... and WOT.... same as not pressing it....

it doesn't even stall out.....(just sounds a little leaner - breathy)

So if you read above on the link you will get an idea of some of the suggestions....

and I must say.... the car starts up and idles well......

The hoses look good..... fuel filter---[i bypassed it no change in problem]

The Tps... I tested it as suggested.... the outer wires... were good....

and the center wire... I stuck a needle in wire and tested while connected

It sweeps fine..... up to like 5 volts...........

I have not tested the fuel pump pressure.... (I honestly don't think it is at fault

but, it could be electrical, the issue causing pump to not have proper pressure)

** what should fuel pressure be? 15 psi? is it supposed to be constant?

If I could find out where the ECU is and what pin the center wire from the TPS

Goes to....... and testing procedures....

I figure I need to make sure that the wire in the connector for the ecu...

for the tps.... I will check it and sweep it for the voltage... Like I did with the needle

in the wire at the TPS.

So yeah...... Zippo throttle response... this car is dead in the water....

Fairly nice Idle.... for a "flower pot"

Thanks, Micky

go to the following link and find the correct FSM for your car (pick model then year)

all wiring diagrams and such are there - just takes a little digging sometimes to find exactly what you need (they arent labeled very well).

TPS should only show about 4.5v at WOT.

Definitely want to check voltage at the ECU.

Also check for any codes. Clear them and see what comes back.
