Hi can anyone help me please.

My car is with tuner after fitting turbo.

He rang me today and said that there is no voltage from the tps and also the engine coolant sensor.

The car is an eg chassis obd1.

He asked what wiring I've messed with. The only wiring I have done is adding a resistor box and clips for the injectors.

The car ran fine just weeks ago on a chipped p28. The tps worked as I calibrated it on new throttle body a long time back.

Can anyone offer any advice please. I can only think the ecu has died for some reason.

Is there anything I should check????

Thanks.

 

reference voltage,continuity, see what all your tuner messed with,dissect the harness and back trace the wires through the loom, check all ground points and contact patch

 

Im gonna check continuity and grounds on tuesday when I can get up there. Seems weird tho as had no issues until now.
Could the ecu have packed up?
Seems odd as the tps and ect are pinned right next to each other at the ecu.

 

i think your tuner fucked up and doesnt want you to know he fucked up

 

Fucked up in what way???
Was just dialing in map sensor and I injectors. Just to get it running.
Says no signal from tps.
And the ect is showing 126 degrees constantly.

 

sounds really odd when youve had no issues then you let someone else touch your vehicle and all of a sudden you have issues is all im saying i let a buddy of mine borrow a truck for a month so he could get on his feet it was returned with oil leaks blown driver hg and the trans slipping before that i had no issues didnt care though i turned around and sold it to cap program for 1500 for not passing smog

 

Solved today. Was purely j12 on ecu stopping datalog from seeing sensors.
