sr startup problem, no fuel. please help.

[stevejames3]

Hey, im at the end of my sr swap. and i went to do a quick start-up, check stuff out and its not fireing up. it cranks good, its getting spark and the fuel system has fuel, just wont start. fuel pump is working but the cylinders arent getting any fuel....it seems to not be getting any injector pulse. am i maybe missing a ground or a plug somewhere? yuri(does all heavythrottle stuff) did my harness. i have a s13 with redtop. would the cas have anything to do with this. just trying to get this running so i can start putting it all back together and tune it. thanks for any help. Steve

make sure you didn't get your fuel lines swapped. also make sure none of your hoses has come off especially your intercooler piping bc maf will think one thing while tour tb is getting something else. also double check your wirings at those two plug

I have seen this problem time and time again, check the stock fuel rail for any bends or kinks. When the engine is pulled sometimes they like to attach things to the fuel rail. This is more than likely the case.FYI be sure to pick up a 255 lph fuel pump

i contacted yuri (does all heavythrottles wires harnesses, also mine) said the plugs were nothing, like an extra option that shouldnt be plugged in. and i do have the 255. im gonna check timing and make sure im not getting injector pulse.

Put starting fluid in the intake manifold. The engine should fire, if it continues to run then you have fuel and the engine just wasn't optimal enough to start on it's own (seen it numerous times), or if it fires a few times and dies then you have no fuel injection.

You can also pull the rail and visually check for injector firing, or you can pull out the CAS, turn the ign. power to ON, and listen for injector tick.

took off the fuel rail. only pulse in the first injector (close to bumper) so i replaced them with a set of 480 s15 blacktop inj (was gonna get it running on the stockers) and they all fire. must have been bad/clogged inj. so im getting fuel. getting spark, compression is low in the back 2 cyl. 105 and 130 if im not mistaken. still not turning over. hhmmm. this is my 3rd motor, ive waited for 5 months(getting hard to find parts so on and so forth) to get this running and now this. im so pissed......blah

I've seen engines pick up compression as they get ran in again. So the engine is not starting? With the 480s it will be hard for the engine to get started, I would dump alot of starting fluid in the intake manifold. It will start with the 480's, but it might not stay running. Crank open the IACV, advance the timing, and try not to give it any throttle.

you think something might be wrong with the TPS?

Possible, but engines generally start just fine with a TPS malfunction. They just have stuttering or surging issues. He could always unplug it.

[/quote]yeah, i have the emanage. just wanted to start it up, so i could start putting bumpers and hood and put the car back together so i could drive it to go tune it.

Starting fluid.

Starting fluid.

Ok, heres where i am with this. im getting fuel (spark plug smells like it should be getting more). getting really weak spark. did some starting fluid, backfired. cranks and backfired a few times like it wants to start. i put on 2 more grounds. one going from the fuel injector grounds(on the intake manifold) to the strut area. and the valve cover to strut area(oposite side). maf is hooked up but intercooler piping isnt solid, had it off for starting fluid and ****. does this sound like a timing problem? cas problem? ground problem oh also i got ecu code 55. if i get this to turn over, its put back together, give it a rough tune with the greddy, break it in. and tune it again. PLEASE help. im running out of ideas and getting kinda pissed.
