Thread: Weird injector problem.

No, I have a realtime ECU so I just changed the program for 370s.

i had a very similar problem and it ended up being my stock fuel pump. It did put out some fuel psi, but not a whole lot. I thought there was pressure in the lines, but when I pulled the hose off and cranked the vehicle over, I didn't have a ton of fuel output. A good way to check it - pull off the main line off the filter and put a piece of cardboard or rag on the hose then crank it, MAKING SURE TO INSULATE IT INCASE OF A SPARK, AS THIS WILL CAUSE FIRE.

Fuel pump is fine, its a walbro 255. And once I got the 370s in, I had to adjust the fpr, because it jumped up to 80psi.

But car has been running fine with the 370s at 4 bar for almost week now.

I have a set off 50 lbs that I will sell you cheap if you need new injectors. Let me know.

Nah, don't think I'll go that route again. I'll stick with the side feeds, I'll just upgrade those eventually.
