    Anyone with some Suzuki knowledge care to help?

    I have an 89 Suzuki Sidekick and have an reoccurring issue I can’t seem to figure out. It seems that the injector won’t pulse and I’m not getting any fuel. I had this issue before and had new capacitors laser welded into the ECM but after only running a couple of times (maybe 6hrs total) it’s not spraying fuel. I know for certain that it’s getting fuel and it’s got good pressure but still nothing. I can get it to sputter for about 3 seconds max when I try to fire it, but it runs off of carb cleaner just fine. I had it running last weekend and it was doing great, now it wouldn’t pull off of the trailer on its own. I did have the same issue when I had it out last time and found that the coolant temp sensor was unplugged, after plugging it back in the zuki ran great. Since their cheap I ordered a new temp sensor to give that a shot but I have my doubts. This thing is seriously hacked together and finding an electrical issue would be next to impossible IMHO. I’m thinking the zuki may have wheeled it’s final trip...

    Maybe start with adding some more grounds in the critical spots? Just a first "easy" step.

    Nope but I can probably rig up a test light and a paper clip to get the job done. I’ll throw a couple more ground wires on it too.

    Is there a way to Hotwire the injectors? And yes check grounds, grounds, grounds

    I thought about trying to Hotwire the incector but have read about that frying them from too much amperage. I’m sure I could just resistors or something but I’m not that great with electronics on that level. Basically I think it’s time it finds a new home.
