Finally started today! The fuel injectors were dirty and I think he said one of the valves was stuck because of the dirt as well. Now that my friend has cleaned the fuel system it starts and the idle is better. Still idles fast and surges when it warms up though. He thinks that a new IAC valve will fix the fast idle, so hopefully that's all it is and I'm on the home straight now.

We're hopeing for you.

We're hopeing for you.

Thanks

I've installed a new IAC valve in the car and it seems to have largely restored the car to working order. Idles fast when it's cold and slows down to a smidge under 1000 rpm when it's warmed up.

Cool, that's what it does.

wonder if that's why mine runs at 1500 most of the time.. sometimes it will be 8-900 like it should, but mostly stays at 1500

When you park it for a few minutes, the IAC will warm up and it will idle properly, after you run it a few minutes it will go back up.

Have you tried testing the thermostat? I'm not going to guaranty it will help but it could at least be worth looking into if you want.

This is extremely promising information. Do you happen to know what your mechanic did to clean the injectors?

He used a GLR Injection Technologies machine - used to be called Mr Injector.

Well my Capri is dead again but at least I know why it won't start this time, the fuel injectors aren't receiving their electronic signal to fire. The ecu, distributor electronics and map sensor have all been tested, the ecu and map sensor are both ok and the dizzy electronics was inconclusive.

My prime suspect at the moment is the dizzy electronics because the seals have failed and oil is leaking into the dizzy. But I was wondering if there's anything else worth checking out that could cause the injectors not to receive a signal?

[Rocketman]

When you crank the engine, does the tachometer bounce? If not that is a classic sign of a failed ingitor module in the distributor, a fairly common issue

[Blobfish]

I thought it still bounced, but now that you ask I can't actually remember with certainty. And I haven't got those bits back that I got tested so I can't check it either
