Saturday: Changed to a Walboro 255 fuel pump. I took my baby for a test drive. I had to wait for my O2 to warm up to make sure I was getting a correct reading on my A/F. I came back to the shop and layed into the throttle. Came to about 50-60 and BAM!! nothing. Check engine came on car was dead. I rolled to a stop and turned it off and tried to restart. nothing. Constant check engine light. No fuel pump activity at all.

So I changed the main relay. nothing. My mechanic bypassed the relay and the pump started. Now I am getting very upset. I still have a constant CEL. And the new main relay does not click. The ECU does not flash once when the key is put in either. All fuses check out as well.

Any ideas?

Thanks.

 

Check all of your fuses. I think the one labeled starter selinoid is the one you're looking for (under dash 10amp). I had the same thing happen. I was came down an off ramp, nailed 2nd gear, and it just died. I had just installed a walbro 255 about 2 days before. The car died and wouldn't start. I tried similar things to what you were saying. I looked at the fuses, and didn't notice the starter one, but in the end... that's what it was. I rechecked the fuses, found that one blown, replaced it, and the car fired and has run ever since.

I have no idea what caused it to blow. The only thing I can figure is that the fuse was so old and had always had the exact same current through it. That little bit of extra current may have caused it to blow. Doesn't really make sense, but then again it didn't look like a normal blow out of a fuse. It looked like it just got a little warm and then broke.

I know it sounds simple, but check it.

I just read the last part of your post... sorry. I should delete, but I'll leave this for anyone in the future that searches for this topic... Sorry about that. I'm an idiot that doesn't read.

Thanks though. I will have my mechanic re-check all fuses anyways. Just to make sure: if the starter fuse is blown then the starter would not work.

I have auto start on my car alarm and I think this may be fuggin things up too. Everytime we hooked up the battery the car would try to start. Damn electronics...

 

Mine still cranked with the fuse blown, the fuel pump just wouldn't get juice. I may be wrong about what the fuse was labeled, but I remember it having something to do with the starter, and no indication of it being related to the pump.

Sorry I wasn't any help on this one though. Good luck.

 

Yeah, you are correct. It is the starter signal fuse or something. It blows when you put a bigger pump in the cars almost all the time. Upgrade the fuse to a higher amperage one.

I figured my problem out last night. I found that fuse #14 was blown to bits. I guess I didn't check to well. I have traced it to lead to the ECU and 3 other inputs. But this makes sense now because my ECU had no power. I replaced it with a 20A fuse and it works great now. Just waaaaay too much fuel pressure now.

 

Is that the same one as the starter signal or whatever?

 

Nope, not the same. The description of Fuse 14 from the fuse cover is 'Altenator Solenoid valve'

 

*a Note...

Sometimes if your fuel pump is not turning on (car is a no start) check the fuel pump ground right off the T-stat housing a 10mm bolt.. After doing a bunch of motor swaps and sometimes forgeting it really sucks

Been there, done that! Spent three nights scratching my head on that one...
