Well I finally finished my 355 with the HSR fuel injection to go into my 92 trans am. But the dang thing won't start. It turns over and tries to start but fires for only a second and then dies. I can keep it runnin with my hand on the throttle but that's about it. I have fuel pressure the plug and wires are new. But I'm a little skeptical about a couple of things. Number one the bolts to hold down the dist have stripped out the holes in the dist base. I tried to rethread the holes but I just can't get it to clamp down very tight. THe cap will move side to side quit a bit. Not sure how else to fix that besides get a new dist. The second is the hsr intake. I noticed that the seal around the gasket is not completely covered. See the heads were ported out to a 1206 gasket and I was not quick enough to realize the hsr calls for a 1205 gasket. But I read ears can be welded on to the intake to make it cover the entire gasket. My question is would either of those problems cause it to not stay running? I thought the intake might be alright because it looked sealed. I could not see any openings but I could be wrong. Thanks for the help I'm leaving for Iraq in a couple of months and really want this running before I leave. So any help would be greatly appreciated.

No opinions?

When you hand throttle it does it run alright, I mean is it missing, fartin, poppin, anything?

If your intake gasket is leaking yes it may not stay running.

Plus you need to get your timing dialed in. Someone needs to turn the dist, while the other works the throttle to keep it running (Connector unplugged) and set timing.

My HSR was a real PITA until I got it tuned. Looks like you have some aftermarket heads so I'm assuming cam change too. You're going to need some tuning. Your best bet is to crank the throttle open with the screw and slowely tune it down to an idle.

If nothing else, that certainly does LOOK badass!!

And thank you so much for your service to our country. Be safe over there.

Boss had a good point. I saw your sig after I posted. Your stock bin (GM tune) isn't adequate to keep her running or idling with your mods. You'll need to do some tuning. DON'T go paying hundreds of dollars to get a premade chip or pay some service to send you one based on your mods. There is no replacement for tuning, taking for a drive, retuning, repeated. Hearing your leaving for a tour I realize that might not be possible to do in the timing but please, don't do it. Too many people have gotten burned or ended up unsatisfied with made to order custom chips.
I put in a fresh 383 with Dart 215cc heads, custom cam, TPIS manifold, siamesed runners, 58mm TB and a VERY worked over plenum. I had to change alot to get her to run and even idle.

As far as the missing I can't really tell. With my new oil pan the exhaust did not want to fit right so it's open headers for right now. Sounds sweet tho. But from what I could tell it didn't seem too odd. And I had planned on taking to a shop in OKC to have it tuned, but I wanted to make sure there were no leaks or major problems before I did since the shop is over an hour from me and I'll have to tow it there. But I have to have it least running before I take it there. I'm just stumped is there a way to tell if the intake leaks without it running? The dist has to be a big problem I mean you can move the cap with ease back and forth. As far as the timing I don't think that will help. It should run at TDC regardless. If it is because of the stock chip how in the heck could it be tuned if it won't stay running? I mean I have an Ostrich and I could do some tweaking, enough to get it running maybe. I'm no expert but I understand the basics.
Thanks BOSS 357 I will do my best and that's a pretty sweet ride you got there too.

Meyer, if you have an ostrich and tunerpro you're almost there. Just create a tune knowing the basics. Build off the stock tune. You'll need a little more VE (volumetric effeciency) and spark at idle for sure with your setup. I'd poke around at 23-25 degrees of timing at idle. You'll also want to reset your IAC motor and confirm your TPS voltage. That'd be a start atleast to get it to idle. You are right on the dizzy cap though, you need to fix that somehow or just replace the dizzy. Can you get a bolt to go all the way through then put a nut on the end of it underneath that plate it would normally screw into?

yeah it needs tuned more than likely. crank fuel changes at startup to get it to run and stay running and then go from there.

i dont like the 1206 ports on the head mating to the 1205 HSR. i probly wont cover the ports well IF you have a HSR that doesnt have excess material that can handle a 1206 port. Those are the new HSR's within the last year of production. Visibly different on the port flanges, you'll notice more material around the ports if its a newer design

yeah you will need to fix your dizzy problem. Then set base timing and lock it there.

Just throwing this out there would it be possible that my valves are too tight. I know it will not run well at all with a stock tune but when I first built this motor it was identical except for the edelbrock tpi. It would run but run like crap. So I figure with the same setup but with hsr it should at least fire up. I'm gonna order a new dist and call the machine shop to see how much it would be to have the intake welded and go ahead and loosen my valves up a little bit and see if that helps. I just need to make sure nothing leaks before I take it for a real tune. I appreciate everyones input. Looks like it might not be done in time now, but at least it will be close. Thanks again.

still hydraulic roller right? reset valve lash/preload. do it the intake closing/exhaust opening way. As the exhaust valve begins to open, set intake valve side lifter preload. tighten 1/4-1/2 turn past zero lash point which is when pushrod tightens up and doesnt spin easily.

but i dont think thats your major issue with starting, HSR should fire but definately needs tuned compared to TPI its a different design thats for sure

Well have some good news. It is running. I took everyones advice and I adjusted the throttle open got it running set the timing and then adjusted the throttle back down to about 800rpm. So I appreciate everyone's help. I didn't leave it running for long tho, in fear of damaging something. Like I said the exhaust is not hooked up and I can't hear if anything is making any strange noises. So I guess my next stop is the exhaust shop and then on to some tuning. But thanks to everyones help. I'm sure I'll be back on here again with some other problem. I seem to be a magnet for them.
