Has anyone had a problem with escos overfuelling to a point where it wont start?

have change map, cts, fuel pressure regulator, leads and plugs.
had ecu checked ok. is it possible for a chip to just give up? or need remapping?

thanks

john

Check the TPS sensor, sounds a bit like it m8

JohnL

never thought of that... cheers mate will do. any ideas of how to test or just buy a new one and hope?

do these go often?

i had this problem also. does the fuel pump prime for a few seconds then cut out or does it run constantly. if it runs constantly try taking the chip out and try that. i took the chip out of mine and it started once i cleaned the plugs and no problems since.

hope this helps scott

Hi scott, thanks for reply, fuel pump kicks in and then cuts out like it used to.
can i just take a chip out? will it still run?

I have a collins stage 1 (see pic below)

You need a voltmeter, and measure the voltage with egnition on, measure the voltage in full throttle and no throttle.
cant recall the ecact data tho sorry.
BUT it has a LOT to do with the fueling

hi john im not sure how yours would work as mine is the small turbo cossie and the chip just plugs into the side of the ecu.

JohnL

will have a go, its in a bit of a tricky place to get to..

how do i test the voltage on it? as in where will i put wires for testing

And no, it would`t start whitout chip

JohnL

cheers for that mate!

have had it taken to a garage via rac and they have had it plugged into code reader and brought up a few error codes so will keep posted incase anyone has this problem again...

Can a tps sensor die in such a way that it tells the ecu its on full throttle?
