Hi, My 1992 SPI was fine up to a couple of weeks back now will not start easily, plenty of fuel & spark, can hear the fuel pump when we first turn on but

I'm not an SPi owner, but have you tried the little elbow and vac pipe from the ecu to the injection thingy?:)

Hi, My 1992 SPI was fine up to a couple of weeks back now will not start easily, plenty of fuel & spark, can hear the fuel pump when we first turn on but will not fire up. Changed the water temperature sensor when I first got it (4 / 5 months ago) as it was running fast & rich, that seamed to improve things but now the starting issue Any help would be very welcome ??

What's the rotor arm like? The dizzy on the SPi isn't ysed for timing but it still uses the rotor to distribute the spark. Also heck the crank sensor is clean. It's bolted into the flywheel housing behind the starter. This has caused me an issue in the past.

Maybe someone wot is kompu'a literate can link Geoffs request to another with a similar starting prob a little while ago. If I was even semi literate I'd do it. A bit of physics and maths but computers........ well, you've got the wrong man!

Does the Stepper motor move the arm on the throttle body? On ignition switched on and then off it should move the arm over then back. Will it start at all and the water sensor I presume you mean the hard to reach brown one under the Throttle body The fuel pump only runs noisy till it reaches full normal fuel pressure. How are the spark plugs, wet, black and messed up or the wrong sort.

Measure the spark leads. Clean all connection parts.
What spark plugs do you have?
Replace all those vac pipes with elbows to Samco 3mm silicon pipes from Samco Motorsports. You don't need eblows anylonger as you are stickung the silicon tubes straight on the corresponding nipples. I have those since 3 years and not any longer any problems.
it also happens that the vacuum pipes after changing the coolant temperature sensor have been wrongly connected (there are two nipples below the manifold)
Check the dizzy if there is no corrosion or missing contacts. It also happens that the dizzy has bee wrongly built-in.
Check the petrol trap - it is the little box below the 4-fuse-box with a green and a black nipple where vac pipes are connected. Check if there is gasoline in the box.
