97 S10 getting a LQ4
I have the weld Pro Stars, MT tires, radiator with fans, Race mufflers and some misc stuff coming this week.
Oh, and which wire is ODB2 at the plug under the dash? My wiring diagrams in the Haynes manual suck bad. I need a shop manual.
Got the dash buttoned back up after wiring up the new gauges and the ECM. I need to solve one issue though. I turn on the running lights and everything works fine. Turn on the headlights and the dash lights go out, the turn signal indicators on the dash come on and the 5 wire (relay)? under the dash starts buzzing like a bad connection. I am going to look tonight to see if there is a ground up front that didn't get hooked back up. I hope that's all it is. Did I ever mention I hate wiring? LOL
Rear end and driveshaft are installed. Need to get a couple fittings for the brake lines.
Only thing left is the radiator up front and a little wiring cleanup and then I can put the hood back on.

So the plan is that this weekend, I will be able to drive it if I can get it to the exhaust shop to get the true duals completed. I am getting slightly excited.
Also came home and found some sexy at my gate.
Got the radiator today. Looks good but have to cut a bunch of metal to get it to fit. Opened the 2nd box that should have been the fans and shroud, it was another radiator. LOL So I am now waiting again for the parts to finish.

Well I cut one coil off the front springs and it sits nice now. About 2" drop in the front. Looks good for now, may go lower later.
Drove it night before last up and down the street real quick. Open headers so only got a couple of blasts. Runs great engine wise. Trany acts like it has a stall converter and I am sure it doesn't. So I am going to change the trany filter and fluid to see if that helps. Just slips like a stall but get the rpm up and it runs and shifts great.
Only issue it had other than the trany was wiring I think. Not sure what it is. The ABS and Brake light stays on and the warning tone stays on. Even with just the key in and in the off position with doors closed and no lights on, the warning sound stays on for some reason. So I need to check this out, but I may not figure it out. Again, I am not a wiring person. Anyone want to come by and help? Seriously.
Went to load it on the trailer yesterday to take it for the exhaust and wouldn't start. Fuel pump wouldn't run. Found a bad fuse, swapped it and no go. Put straight power to the pump and nope. Still wont spin. Its an Aeromotive A1000 that I bought here from a member. Worked fine until yesterday. Ordered an A750 last night since its smaller and wont cause me as much of a fuel heating issue on a stock engine and 12 gallon fuel cell,
Looking good!
Thanks again

So I called Aeromotive and they could rebuild this for 200.00. Then I would need to buy a 350.00 controller to ramp down the pump for my needs. But they said the best pump for my engine is an A750. 60psi and 450 lbs per hour. Good from 150 to 800hp engines. So it wont burn up or heat the fuel too much trying to supply more than the engine needs. And it doesn't need the controller. So I bought one that will be here tomorrow. I'll post pictures once its mounted. Will go in the place of the A1000 so it will be easy.
As for pressures. I was told by guys on here that they need a 60psi supply. With the big A1000 pump it would prime right to 60 psi and with engine running it would be 40-45 psi at idle or light revving. You need to supply more pressure than the engine needs so that the engine has extra pressure or flow when needed, like full throttle. If you are only supplying 45psi and already at maximum flow for the pump, you will starve the engine if it needs more at any certain time. So the pump needs to supply extra and that extra gets returned to the fuel tank since its not needed trough the regulator and return line. All vehicles are designed this way. I would get a 60psi pump.
Hope all this helps and didn't confuse you.
Loaded it on the trailer and took it for an exhaust install yesterday. I'll pick it up Monday am since I will be out of town this weekend. I would have built the exhaust myself but the driver side took some precise bends to get from the header flange to the straight run next to the transmission. Also found out while it was in the air for a transmission filter and fluid change, that I have no rear braking. Everything bled out fine but it now has a very soft pedal. So I will have to bleed it all again to see if it helps. Im hoping it isn't an ABS issue.
And the last item will be finding a performance friendly inspector here in Hays county. Only thing missing is cats, but they don't sniff here since we are not an emission county.
