One could only hope. I did check the fusible links but you do have me questioning the ECi relay. I need to get out there and check the power leads at the ecu and see what I have. I’m itching to drive this thing since I’ve fixed a bunch of issues and up dated some of the parts. I’ll definitely check out what I’ve got at the switch though. Thanks for the input!

Thank you. I saw the schematic and was like: mmmmm….🤔 wasn’t sure if I needed to keep looking or not. I do need to replace it though, man did it look bad- lol. Soon as I can figure out what’s going on with the signal I’ll be back on track and can continue tuning. Hopefully it’s something stupid, and not anything big. This is the first major issue I’ve ever had with it- William- 1987 Conquest TSi

Ok so this is a bit simple in title, but it’s not actually. Vehicle: My car is a 1987 (I know they’re the most problematic 😫) Conquest TSi, with an HKS Exhaust, HKS Turbo inlet kit, TEP Down Pipe and mid pipe, and a FP Blue from a WRX, modified to work on my hot housing. It’s essentially a TDO5-16G. The car has been laid up for a few years, so I went through it to put it back on the road. Installed the following: 255 Walbro Fuel Pump New R/C injectors (750 primary, 1050 secondary) New MKS Motorsports injector harness kit New Brake Master Cylinder New MKS Stainless Steel Brake lines New MKS Billet Steering Coupler New upper strut mounts and I ditched my Apexi Super AFC-2 and installed a MAP ECU V1 piggyback to convert to speed density because I no longer trusted my factory Karman Vortex MAF . When I initially got the conversion done and built a base map the car ran fine. Out of nowhere when I was ready to start street tuning it under load it started die’n when it warmed up. A little digging and testing revealed I had a problem with the pick up coil, so I ordered another distributor and it wound up being trash right out of the box. That forced me to dig up the original dizzy. I tested the pick up coil and it was still good, so I swapped it in, made new pig tails to plug it to the harness and no start. Tested the pick up coil again. 1170 ohms. Well that should be good. Checked the injection housing and it’s dry as a bone. Checked the spark. Nothing. Looked up the wiring schematics in my manual and decided to try tossing in the little black box of death - (spare igniter). Still nothing. Looked again at the schematics and noticed that the knock sensor goes through the knock box. Checked my knock sensor and it’s totally smoked. My question is this: Does anyone know if the knock sensor and its harness being shorted can take out the ecu, ignitor module, or perhaps completely block the pick up signal from the dizzy? I’m beginning to wonder if the knock sensor took out the pick up coil in my dizzy before I lost all rpm signal. I don’t hear the fuel pump or anything, so I know the ecu isn’t commanding it on. Anyone have any ideas? About the only thing I hadn’t done is bought another eci relay, but im skeptical that’s the issue because it’s always started up till now. Thanks for everyone’s input in advance! William- 1987 Conquest TSi

You’re right, I didn’t 😆 I just couldn’t stay away! Lol

Thank you! I absolutely love this thing! It’s been a great car. Eventually I’d like to have it reshot the same color with a few light modifications to the paint code to give it more depth, but all in all I’m happy with it- Now I just need to mod the Magna MPi manifold I’ve had for like, 5yrs. 😩

Yes, That would be awesome! And thank you!

Thanks- the color grew on me for sure, it’s definitely different. First time I’ve ever had a Palermo gray car. My Aunt’s Quest was red and my previous Starion was black.

Hello everyone. So I’m a old member, but I haven’t been on in a long time. I wasn’t able to reactivate my account. My old name on here was 1rst Gear. I had an 88’ Starion ESi-R previously, and that car eventually wound up with a friend. I wasn’t Starion-less for long though. About 3yrs later I bought my 87’ Conquest TSi. I’ve had it for about 6yrs and kind of stayed to myself. Now it’s time to comeback to Starquest club. I tossed a photo of the Quest in so y’all can see one of 12 money pits I have- 😆
