yes but not running pump during crank
Done with this I am going to take it out and really look at the harness to see if some wires need more repair or relocation mostly grounds and stuff.
Ok I will try different battery tommorow
engine is stock got a complete system off a 1988 chevy truck with a 350 and my 85 blazer has a 350 so pretty much the same motor.
I have a 92 buick that i can swap parts from I may start doing some swaps.
fuel tank/pump/filter are all new if I jumper pump it starts ok. I just have crappy accleration that really bothers me.
How do I check the AE? I have good fuel pressure right at 13. I still have a low voltage during crank at fuel pump relay that keeps i think It keeps from picking druing crank.
Battery checks good at 2 different stores. I can get it to start whenever I need to by just cranking it a few times until oil pressure builds up. It seems to run good except when accelerating I can...
Battery is new. It look like the + cable has to much voltage drop during crank. I jumpered from pos terminal to the firewall terminal block and it fired right up so going to replace that cable and...
Finally got back to this. All wires are hooked up and come on when they are supposed to(i think) but a1 drops to 9.3v when cranking which isn't enough to pick relay. I tracked it back to the pink...
I will look for that tomorrow
IU think it is only a 4 pin module. what I have read is pump should come on during crank. it is a 7747 ECM. motor is older so it can take a little bit for oil pressure to come up to turn on pump...
So I finally got the truck to run pretty good but is hard to start.
I get 2 sec fuel pump at key on, no pump during crank then pump on after crank stop. I have crank signal at c9 all the way into...
OK I am back with more questions.
I got everything up and running with no error codes. I have a 7747 ecm with a chip done by Dave W. stock except 700r4 and smog removed.
now it runs fuel pump for...
Got it thats what i was looking for. I only have the white plug and it has a yellow wire instead of brown in it, since I only have cruise in 85. Thanks to all who helped out.
Just wasn't sure if I was supposed to use the raw signal or the buffered one.
Mine looks like that but has a yellow wire coming out of the part not drown. I was not sure if you connected it before the buffer part or after it.
I don't have a brown wire. red green black come out of speedo head and pink black yellow come out of what I think is the buffer.
I have an 85 chevy k5. I found the parts up at the speedometer and need to know what I hook up my vss input to? do I use the yellow wire that comes out of the little green adapter or use the wire...
I am getting this put together and want to know if I can get one of you guys to help burn me a chip? i want to learn all the the hardware stuff with this conversion so then will work on burning chip...
Got tunerpro and playing with it/ learning what it can do.
Fuel tank and pump on the way so i am going to start this. My question now is about EGR stuff, i will be getting rid of it do i need to program out that stuff or does it run ok with it just...
I have to order a new fuel tank before i can start this project so it may be a week or so before i start, then i will get with you guys on a chip and maybe the harness
ow much do you want for the harness?
for the first one I wasn't sure I wanted to spend the money on burning stuff. I may take you up on this, what do I need for you to do this?
