If you've got to do that much work, I'd skip it! That relay shouldn't be necessary, if your other ignition and start circuit wiring is good, and your ignition switch and security relay are good. With RHD, your wiring to the starter might be shorter than these LHD cars! (Assuming your RHD...

If that wire is actually connected to 87 (not 87a) and goes to the starter solenoid, the PO was trying to assure that a full 12 v. is applied to the solenoid. He may have been fighting a hard starting situation and wanted to be sure there was a full 12 v. applied to the solenoid. That purple...

Your other requests for answers to this question were ignored because you "hijacked" the threads already in process that were NOT related to your question. That won't earn you any friends! You need to start a new post for a new question. I replaced the window mechanisms in my '84, after...

The manual knob is on the bottom of each headlight motor for the '84 - '87 Corvettes. Here's an easier way to change the headlight: 1. Turn on your headlights to open the doors. 2. Turn off the headlights, and then quickly pull the headlight switch out to the parking light position. This...

Tex Pete, I see you're asking the same questions here, too. That's the connector for the cruise control wiring from the turn signal lever. :ugh

How long was the car sitting? How many garages do you have? How far is it between your garages? You need a Factory Service Manual (FSM). Much better than online information. Try eBay. When the engine is running, is the spray pattern from your fuel injectors smooth and equal between...

Are you sure it's not just stuck on the weatherstrip? Try lifting the gas lid so you have room to get your fingers under the glass. :w

I would agree. I may have been mislead by your talk of upgrading your throttle bodies. You've got enough spare parts to get your car back on the road, then do whatever you want with the other assemblies. You are probably aware that the front and rear injectors are different sizes, and...

If you've got a spare top plate with good throttle bodies, which won't even need balancing, that sure sounds like the right answer to me! That's an easy swap! Use a good grade of RTV and you won't even need a new gasket! Has your intake manifold been ported? :thumb

Are you getting 12 v. at the fuel pump connector? Testing first is much better than throwing parts at a problem! :w

It sounds to me like you may have put the magnets into the motor backwards. :w

You did good! That'll make you really enjoy the victory! That's a difficult project, and your success will encourage others that it CAN be done! :happyanim:

This is true, until you run the compressor! An overcharged system can easily exceed 400 psi! You are charging thru the low pressure port, and liquid refrigerant into the compressor can cause havoc! With the compressor running, the low side pressure will be reduced, and therefore the higher...

If the relay sockets are hot (temperature), focus on that problem! Check for burned wires to the sockets, or scorched electrical contacts in the sockets. If the relay itself is hot, it may need to be replaced. :w

Step #1 for starting a newly assembled engine: Be sure ignition timing is correct! Dist. rotor on cyl #1 position, and vibration damper timing marks at TDC (or 6 deg. BTDC) on compression stroke! :w

The "entry angle of approach" listed in my '84 MVMA Technical Specifications book is 11.4 degrees. I trimmed about 3/4 inch off the bottom of my air dam, which I don't believe causes any cooling problems. The "departure angle" is 34.8 deg. MVMA: Motor Vehicle Manufacturers Assoc.

So you're testing all the forums to see who has the best answer?

hotrod2, the OP's '84 is much different than your '85. The fuel pressure regulator is built into the TBI (throttle body injector) and the fuel pressure is more like 12-13 psi, not 39! And there is no "fuel rail". Thanks for trying, though. :eyerole

Do you have a good spray pattern from both injectors during cranking and when the engine is "dying" on you?

? I've read this many times, but I can't figure out what you are trying to say. Is that all one sentence, or several mixed together? What kind of car is this? It doesn't appear to be a C4. If you think of this set-up as if it had ignition points in the distributor, the voltage on the negative...
