1977 280z 2+2

interested

Ok so update I found the guys contact and I PMed him. So got that kit on order. So if I replace injector connectors and it still doesn't start what could be the cause? It will turn over and catch once in a while but other than that, just turns

do you still have a kit for a 77 280z?

Thanks I'll do that. And the car has been in the same spot for 2 weeks Edit: did the search all I got was alternator upgrades edit: found the thread..left a post but that thread hasnt been active since 2013.

Well the search function won't allow 4 characters or less per word lol gm amp are ignored when searching gm amp connectors lol mind linking the thread?

Is the kit you're referring to called 460/755 piece weather pack kit by diyautotune?

Thanks for the detailed replies. Ive heard only great things about deoxit. I'll see if my local radio shack is still in business and go stock up. For the injectors I'll take a look at the junkyards around the area otherwise I'll probably go for the GM AMP connectors. Also a side note, what year Toyota AFM will work? Edit: Just checked out the site wiring specialties but they don't have anything for L28 specific engines. What engine had the same style injector connectors?

I downloaded it earlier today however I wasn't able to pinpoint the cause. Tony would wd40 be an aporpriate cleaning agent for ECU contacts? Also where do I start for harness connectors? I've never messed with any ECU or harness stuff.

I did a compression test and all cylinders are 120-125psi. Spark plugs were black and smelled of gas but the contacts were good.

I replaced the fuel pump with a msd 2225 . I even went ad far as insulating it per Atlantic z's method. Car won't start at all now. Pump still comes on very clearly with key in on position. When I try to crank it sounds like it wants to start but not on all cylinders. What do you guys suggest I try next?

I have a pair in good shape. They are from a 2+2.

the fuel rail i ordered is a pallnet and it has the fuel pressure gauge built in. so i think ill just replace the fuel pump until then. any recommendations as far as brand? and as far as the misfire? would a band pump cause that too?

All those things that have been listed as replaced have been replaced within 2 months. Sunday I replaced AFM and water temp sensor. Spark plugs/wires, distributor/cap/rotor maybe a 3 weeks ago. Fuel filter in December. I replaced them because I thought it'd fix the issue. But I have it narrowed down to cold start valve or injectors. Also when I have the key in the 'on' position, I can hear the fuel pump whining. This is odd because I have never heard it run with the key in the 'on' position. Is it time to replace it? Also since I'm so low/empty on gas i want to clean it out and replace any old fuel lines. Although I believe the p.o did a lot of maintenance to it.

Hey everyone I'm having problems with my 280z. It will start up cold no problem. After it gets warmed up it will run fine for a while then bog down. Any gas more than 15% pedal down will cause it to bog worse. If it does still limp it sounds like its misfiring. Other time I had it stall on me I was pulled on the side of the road with hood open. Let it cool down and tried it. Started but with misfire. I looked around the engine bay and suddenly it ran like a top. I didn't touch a thing. Currently it won't start;I think I'm out of gas. There is a gaping hole in the exhaust manifold on the 6 cylinder. Things I've replaced: AFM Distributer (e12) Distributer cap & rotor Spark plugs Spark plug wires Water temperature sensor Fuel filter Things I have coming on the way: Pallnet fuel rail Injector o-rings I have new injectors and another stock fuel rail. Oh and 6-2-1 Monza header.

PM sent pallnet.
