Default She wont start, help?! WIRING ISSUES?! Post 29!

Hey all, the poor old girl hasn;t been run for 2 months, and just trying to start it and i have an odd problem.

As soon as i turn the ignition on, the fuel pump clicks on and off randomly, constantly, and the injectors are clicking at the same time as the pump, and obviously it wont start, if you turn it over it tried to kick now and again, but it wont go, sounds relayish to me, but what one and why?!

Any help would be ace, ta!

have you checked the phase sensor is pluged in right or the wires have not broken, have you removed fuel pump relay and turned ignition on to see if injectors still pulse

The injectors are powered from the ECU relay and so if the relay is clicking it means the ECU power would be intermittent as well, hence the pump turning on and off, the relay is yellow and is behind dashboard (Passenger side).

batterys can brake down in side so can just pack up with out warning

the ecu needs a lot of power to operate and thats just 1 thing

got to have a good strong batery on a cosworth

If the relay is clicking in and out it would have to have virtually no power at all as it indicates the relay is unable to energize. If it turns over ok then it won't be that. A week is quite bad tbh so I would think there is something wrong, I have a Clifford and I can leave for weeks although I do notice it takes a bit of power but I was told on here they are no worse then other alarm systems.

Is it defiantly a relay clicking?

It is more likely to be the starter solenoid making the rapid clicking sound as like the starter motor it requires a lot of power to energize IF the battery is the cause.

Its always been the same since it was fitted, this is the 4th brand new battery its had on it (not cheap crap either)

I'll smack some jup leads on it after and see what happens, cheers.

Thats a power problem, the battery may be finished, the starter is having trouble turning, I don't think it's a starter problem itself, if it's jammed you normally get a click. What is the battery reading?

thats not me trying to turn it over, thats just with the ignition on, its jump leaded to my 306 (which is charging at 14.2, even with the cossie connected to it), spins over fine on the starter like that, its something else.

Oh rite I assumed that was you turning it over, yes that sounds like the pump having trouble, which now takes me back to your other thread, is the relay clicking inside the car in tandem with the pump noise?

I am going mad this is the same thread LOL, on 2WD the relays are actually behind the dash, you can do it without removing the dash by putting your head in the foot well and looking up underneath dash, they should be secured by clips, you are looking for a yellow relay, the ECU relay is also yellow so be sure not to confuse the two.

sound like the batteries had it these ignition systems do all sorts of weird and wonderful things when theres lack of power had this on a 4x4 sapp dis battery and charge for a few hours and try again to see if it improves the trouble with these alarms and immobilisers and the recent cold weather is it drains them drastically esp if the cars not in constant use

its definatly not the battery, its fucked 5 battery's since ive had it and always done the same thing, this is completely different, just tried a good battery on it and made no difference. Going to check this relay in a bit, then if i cant find it, im going to set it on fire i think.

Right, the fuse box in the engine bay seems like it may be causing trouble, it has one very melted fuse in it (fuse 11, 30a, unmarked, any idea's?) and the yellow relay (also 11, or xi as its roman numerals) unmarked, not quite melted but looks as if its been hot.
Any idea's people?

Another update, it just backfired. WITHOUT it being turned over, just with the ignition on, so it must be sparking on its own as well?! odd odd odd.

Fuse number 11 IIRC is the cooling fans and it's a common problem for these to melt due to the truely rubbish setup Ford gave it, the main reason for which is the fans stay on for to long, on NON Cosworth models this is for the fuel pump/air conditioner on CARBURETTED versions only, all the relays etc you need to be looking at are behind the dash and are part of the engine loom which is unique to this model.

Ideally you need to rewire your fans, plenty of info, diagrams etc on here if you do a search.

The fuel pump suffers a similar problem where by the wiring has built resistance over time and so the pump cannot get the power it needs under load!

The relay sounds like the cooling fans as well (Is it a yellow one?)

it is yellow, yes mate.
The fuel pump has already been rewired with an uprated loom, fan's are next to do.
Beginning to think the ECU is fubar'd to be honest.

Yes they need to, you probably will find they don't actually work at the moment, have you checked CPS at all, maybe thats at fault and giving some sort of duff input?

Have you got a coilpack conversion ?

For some reason they discharge when the ignition is on, so that maybe you backfiring problem

i haven't checked that yet, i considered it but then thought if its not turning over it cant be getting a signal? its not very old, but i'll check it next time i can be bothered with it.
EDIT, yes, it is on a coilpack conversion. Discharge?

they basicly spark when you switch on the ignition.

If there is fuel and air in the cylinder it can fire. It has actualy turned my engine over before.

It maybe worth sending your loom away to be checked. If all the injectors are going its got to be an issue with the CPS/Phase or the wiring too them. Or the ECU

i'm thinking ECU, mainly because the fuel pump is going mental too?

but that could be the ecu getting a signal from the CPS to pulse the pump and injectors. if that makes sense.

If you do decide to have the loom checked, give me a pm as i know if someone that does it.
