[vn1989]

i just put a new wiring loom in my car because my series 1 vn was on gas and the person that installled it soldered wires into the old loom and they ran to a fuel control prossesser and now after replacing the loom i turn the key and the fuel pump doesnt prime and i get no check engine light i checked all the fueses and there all fine i allso checked the fuel pump relay and thats fine aswell im stuck for answers

Does the car still try and turn over?, have you checked the fusible links as well in the engine bay.

A lot of what you are missing is controlled through the ECU , including the check engine light and fuel pump relay. You may have inadvertently fried the ECU if all the fuses, fusible links and relays check out. Before you look to replace this though make sure all your connections are OK including any earths that may have been disconnected then double check everything again including the fuel pump in case it died when using gas for extended periods.

go around the car with a test light n see if u got power to the pump etc first

if u do maybe ur ecu could be fried like 20 buks at a wrecker

all the fuses and relays are good and the fuel pump should be fine because it started before i put the new loom in and disconnected the gas wiring and i will check for power at the fuel pump its self in the morning if i cant figure it out looks like im going 2 an auto elec

bet its an easy fix on the loom where the ecu plugs into it is a plug that plugs into the dash loom (about 20cm away from ecu plugs) and feeds ignition power to the ecu and also does all the check engine light and auto trans wiring etc most people dont plug it in LOL there is also the aldl plug in the same area of loom but its a small plug

thanks for your help delcowizzid i dindnt evern know that

[delcowizzid]

its going now is it

[vn1989]

yeah it is thanks for the advice.. i also did the code thing with shorting out the black and white wire and i think i got 22 the engine light flashed twice paused for about a second and then flashed another 2 times is that how you read it???

[delcowizzid]

yeah 2 lots of flashes should flash once pause then flash twice making code 12 it will do that 3 times then flash the next code 3 times then the next if there is anymore codes if the engine is running it wont flash the first 12 code do it not running. code 22 is tps
