No start!

[rj_gspot]

So after recently upgrading my fuel system and ecu my car simply will not start. I put a wally 255 in and did it correctly. I can hear the pump turn on and i am getting 25 psi at my fuel regulator. I know i need to be at 43 psi but i have adjusted the thing as much as i can and still nothing. I also installed injectors and ecu. The ecu came with a wire to attach to the clutch position sensor and i correctly installed that as well. Any help would be great

So after hours of work still no start. I did get it to cough a few times and wanna start. I got 43 psi at the gauge now so i am still clueless.Help!

 

[nytescion]

put the old ecu in and see if it fires up.

Was it a standard ecu or did you get dsm link or something like that. You need to work on getting the fuel pressure correct first off.

I adjusted my regulator and now i am at 43 psi. I tried the old chip but still not a chance its gonna start. I got a chip from Jeff at Dsmchips.com and it just struggles to start every time. Its so close everytime but still nothing. Any other ideas guys?

How is it struggling to start? Is it cranking but not turning over? It sounds like its a fuel issue. What size injectors did you install?

 

[rj_gspot]

Like the car wants to start but just barely will not stay running. And i installed 750s. Everything i try seems to not work. I am super confused

 

[bpestilence]

How are you trimming the bigger injectors? You haven't really said what kind of ECU you are running.

If you just put 750's in a car without any way to adjust injector timing, it will not run. The AFR will be like 9:1. I tried it in my car for S&G.

 

[rj_gspot]

Well i sent my ecu off to get socketed and a chip burnt for it from Jeff at Dsmchips.com. And i also have an SAFC 2 as well.

After trying to start it, do you smell gas? if so, then you should be getting enough fuel.

The same thing happend to me. I upgraded injectors and when I went to start, it wouldn't start. I thought it was the injectors, but after I put the old ones back in, same problem. Tried changing ecu's, no luck. Everytime I tried, I could smell the gas. Took it to a shop. and it turned out it was the cam sensor that had gone bad.

Also just to confirm, you tried it with the new chip, and with the old chip and no luck on either chip? do you have a spare ECU?

Also did Jeff know that you where going to run 750's?

Ya i wish i had a spare ecu to use just in case thats what it is. Ya I can smell fuel from the engine and exhaust so i know its getting fuel.

Ya i told jef everything i was running. I think i might have him burn me another chip to see if that is what it is. But you would think the stock chip would work at least to start it.

 

[black_gsx]

Def sounds like a fuel issue, but getting a stock ecu in there to see if something went a little off on the chipping sounds like the best place to start. Did you unhook any grounds anywere? I have done that and it wouldnt start for anything. Could be something as simple as that too. G/L!!

 

[rj_gspot]

Ya when i put my ecu back in it came with a wire to splice into the clutch position sensor. I wired it in correctly according to the diagrams. You think that might have anything to do with it? I just replaced my spark plugs and it was definitely a lot closer to starting with the stock chip in.

 

[portnpolish97]

Just a suggestion, But did you by any chance unplug your coolant temp sensor? Thats exactly what happens when you forget to plug it in.

 

[rj_gspot]

Ya when i unplugged the clutch position sensor i unplugged one other sensor so i could have some extra space to splice that wire. It was a pretty big connector and it was right by the clutch pedal. Is that where the coolant sensor is?

 

[sax_man]

Did you ground the ecu?

 

[RoryBarron]

So are you trying to run a safc and a chipped ecu at the same time?

 

[rj_gspot]

Ya when i had to splice the clutch position wire i grounded the ecu as well. And i am running a wideband and data logger

 

[rj_gspot]

Still nothing at all. I have a new chip coming from Jeff so hopefully it will start once thats in.
