hello people
i have a xr2 which i fitted a escort rs turbo engine on completeion the car wouldnt start theres a spark but the injectors arnt injecting till i turn the ignition off none injected whalst cranking can someone please help me it will start but only for about 5 seconds at the most most of the time its just fireing i think this may be beacuse after i switch the ignition switch off it injects fuel into the cylinders so on initial crank its got fuel so starts then dies after alot of cranking with both the cold start valve connected and disconected i inspected the plugs and they were black ???
can anyone help chears
luke

 

is fuel pump priming?

 

hi yes fuel pump is priming

 

SPARK PLUGS ARE BLACK = OVER FUELLING!

ARE U SURE UVE GOT THE SNSOR PLUGS ON THE BACK OF INLET MANIFOLD CORRECT?

BLUE PLUG COLD START
BLACK PLUG AUX AIR DEVICE
YELLOW: THERMO TIME SWITCH
BEIGE :TEMP SENSOR

 

This is my mate just for info.

The pump is priming, there is shitloads of fuel pressure there, but when cranking even with the flap fully depressed there is no fuel spraying from the injectors, the only times we have seen fuel come out the injectors is for a split second when you stop cranking? Its well wierd never seen anything like it?

It should be wired right as i helped him with the wiring, but to be honest KE Jetronic even in the event of a fault will operate in a limited economy and performance mode (as a K Jetronic system), its the fueling issue.

Has anyone ever seen a fault like this?

 

im sure Billycabrio had the same prob after his restore and i think it was a wrong cam that was keepin his valves open

 

Second hand engine

I don't think he saw it running before he had it although it came from a relative i believe?

 

 

new information fuel only sprays from the injectors if when the ignition switch is turned off the fuel pump is still running if the ignition switch is turned off after the fuel pump has stoped running it wont spray when the ignition switch is turned off. i bridged the perminant live terminal on the fuel pump relay to the fuel pump live and the injector continuasly sprays, whats strange is that when cranking the fuel pump can be heard running but doesnt inject without the bridge in place have tryed cranking with bridge in place but doesnt start just fires occasionally
does anyone know whats going on

 

when mine did this it was the cam timing very slightly out...

 

Wiring fault im tellin u luke, i told u them wires on that plug for the hydro electric pressure actuator were the wrong colours

 

Try the metering head. I had this problem when i converted my escort cabrio. Got another 1 and problam solved. just an idea.

 

u reakon a wireing fault then andy

 

just a silly though ive seen the multi plug on the ecu's the wrong way round before

ie plug for ecu was fitted to injection ecu and vice versa!?

 

Have you tried someone elses pinky/purple relay? these have gave me a lot of hassle in the past, I would try and do all the easy things first by using
a known working silver ecu
a known working black ecu
a known working pink relay
& a known work brown relay

that would be my starting point, if nothing else that totally rules out all those components therefore you can concentrate on the wiring.

 

Well, not trying to blow my own trumpet but next time try listening to me when i say somethings wired wrong, and u wana stop listenin to that bloke at your work if hes telling u things like KE Jetronic pulses the fuel flow, its continuous injection..........although we all know its a bit pile of soapy wank.

At least you've found the fault though

 

correct was wireing fault but has now stopped injecting again checking fuel pressure hope to have it running soon
