Have you tried removing the harness plug and throwing 12v across the blades on it to see if it does it's thing? (polarity is not an issue, just 12v + on one and - to the other)
If that works you issue lies with the connection on the TPS or the TPS setting, the fuse near the radiator overflow bottle, the TPS proper, the wiring, or at the extreme, the circut board inside the solinoid plug on the harness.
We checked the fuse and the wiring, but no, so far we just moved the throttle to the point where it activiated the VVT solenoid on another Spider we had sitting nearby, and nothing happened on mine. I'll pursue this week.
Agreed. I did advance the throttle to the stop with the key on and got nothing. I will check for 12V at the fuse, then energize the solenoid separately to see what I get. Aren't there three solenoid wires? Or am I misremembering?
Well I solved it yesterday. The solenoid wasn't stuck after all.
I got 12V at the fuse and at the three-pin plug. I separately tested the solenoid off the car, which clicked fine when hooked up to my go-kart starter battery. Hmmm. Put it all back together and still no action when the throttle was fully opened. So I diddled the various connections a bit, and it turned out to be the Bosch multi-plug on the TPS not making good contact. Wiggled and cleaned a bit, and it works fine now. Thanks all.
Howdy peeps, my apologies if I've posted this thread in the wrong place. Mods, feel free to move it around if needed.
I've converted my EFI 1985 105/115 2.0 Spider to carbs - Runs great! But the car is still operating with both the Bosch ignition and fuel ECUs hooked up. I would like to remove...
1600 GTV with crossover intake, pretty much standard, but for headers and electronic pickup in dizzy.
It seems the local auto parts stores and even our beloved UK/US suppliers seem universally to sell 180 degree (ie straight) plug caps, mostly with long risers which makes the HT leads foul the...
I am in need of an oil change soon before I start my Alfetta for the first time in 40 years, and the Haynes manual says that the recommended oil is 10W/50, but I either can't find it, or it's stupid expensive. Will 10W/40 work instead? Thanks.
I am looking for a Bosch connector to fit the early 81-83 gtv6 dizzy. I am in the final stages on my 87 spider w/ 164s 3.0 swap. I am using the Bosch bim024 ignition module and no fuel injection, 3 Weber idf 40’s on fabricated manifolds. Just trying to find the right connector to finish the...
Hello all I just purchased a 1989 Spider Qudrifoglio. The car has been sitting for 16 years I dropped it off at the mechanics we did a tune up changed fluids refurbished the gas tank and fuel sender and the car feels gutless and won’t rev freely. Has anyone had these problems on there Alfa ?
