Ecu

[MAMOOK]

Knowledge.
Sorry for my ignorance before I start.
Had the capacitors and a small section of track repaired. Replaced the ECU. Nothing. Engine turns over but will not fire up.
Removed a plug and a spark is present. Dropped small amount of fuel into cylinder. Replaced plug and still nothing.
Any ideas appreciated people.

Pull an injector and see if it is firing.

Pull an injector eh? Lol.
I may add that I am an absolute novice when it comes to engines.
I have removed the plastic injector cover to expose the wiring loom. What next?

OK, the Beat injectors are on a common rail, so you'll need to unbolt all three injectors so that you don't undo any of the fuel or electrical connections. Point the injectors in to a dry container and turn the engine over for a few seconds, you should be getting a spray of fuel from each. Please remember that this is petrol, so don't crank it forever as you will be sending a combustible spray in to the air which could catch fire.

As you know you have a spark, the only other variable (provided you have not changed anything else) is the fuel. If you are not getting any fuel then it is likely that you have an ECU issue.

The other option is to borrow an ECU from another Beat. If it works you know that the ECU is the issue, and as it was (largely) working before the repair you'll know that the repair is the issue.

Re swapping another ECU, do you know any other Beat owners near Leeds?

Top man Stu,

I'll give it a go and get back to you.
No Beat owners near to me now that I know of to be honest.

woah there. the fuel rail bolts to the intake and the injectors are sandwiched between them. if you unbolt the fuel rail there is nothing stopping the injectors firing out of the fuel rail and soaking you in fuel when you key on

easiest way to work out if it's spark or fuel is to buy a can of easy start and spray it into the air filter whilst cranking

if it starts and cuts out when you stop spraying, you have a fuel issue. if it doesn't start at all, you have a spark issue.

Removed injectors and turned the engine over, no fuel issuing from them. So I'm guessing it may be faulty repair or component on the ECU?
Opinions, and what to do next please people?
