[Doctor Gollum]

One relay switches the fuel pump, tother the injectors.

I meant swap them with those on tother car, as if either one is faulty, then you'll get the same results... no fuel in the cylinders. I have seen both fail on a handful of cars, and that it's even possible is enough to rule it out.

If you turn the ignition to 2 for a minute, then off and crack the larger fitting on the fuel rail that will confirm whether the pump relay is working. If you then swap them with each other and the result changes then you'll have identified the faulty one.

I appreciate the reluctance to take them from the other car, but it's a free test. And if no change then you might be looking at the pump if you've no pressure at the fuel rail.

A sharp tap of the relays whilst cranking might be enough, likewise slap the bottom of the tank whilst cranking should be enough to get the pump going if the relays check out.

Be advised that the relays are tight, and the one with the larger red and red/blue wires is the injector relay

They live in the box with the ecu and are the same.

Hi matey,
There is petrol coming up alright. Can hear the pump and it gushed out last night when it was cranked

[Doctor Gollum]

Ok, swap the injector relay for one from other car

[STEMO]

Thought we had fuel....no spark?

[Doctor Gollum]

Thought we had fuel....no spark?

Fuel at the rail means just that. Fuel from the injectors is a different issue.

Besides an injector fault or sensor failure should raise a code, relay faults don't.

OK

That is tomorrow's job

OK 

But James said theres no spark  .......

[Terbs]

There wasn't....James took the diss pack off and got a/the plugs out and wired it up to check. We tried a couple of times but there was diddly squat. He also did a compression test which showed perfect compression.
However, to discount everything, I/we will try all the suggestions offered

[Steve B]

Terbert.. how much did you pay for your cheapo one ?  I have this brand new one from VX  sat in the garage

[Terbs]

Hi Steve..
I only paid about £12, so it isn't going to break the bank, but it should see whether it will start or not. If successful, and yours is going spare, I'll give you the nod. Thanks mate

[Webby the Bear]

Forget fuel... you've no spark! 

Try the CS as James previously said 

[powerslinky]

Just fishing for info for future reference here . . . The good Dr. has suggested swopping the mauve relays from another car.

 We have been told  there is no spark ? , as James has tested for this.

 So . . . would/can either of the mauve relays (fuel pump & injectors)
if faulty . . . cause a no spark situation ?

[Kevin Wood]

Yes, I believe so, as one of them powers the ECU and all related systems (although the coil packs are fed straight from the ignition switch).

Thanks Kevin  . . . will log that in the memory bank
