89 camaro rs 350. been sittin for 2 years. needs starter fluid to start most times. no muffler on it at all. will that cause it no to crank or to die while sittin at a red light?

i would try checking my ground cables.try looking up the codes.this can be done for free at the local autozone or someplace like them.
i would also check the alternator/voltage regulator and there grounds.

SOURCE: What is the distributor timing mark for 89 chevy

Is the vacuum hose removed from the dist when the timing is being checked?
Are you connected to the first plug wire (closest to the rad) on the drivers side?
If this is being done.....remove the cap and rotor and check the springs on the mechanical advance,the advance should be tight to the shaft and springs tight.
I would set the base timing on this set up .....at idle speed...... at between 5 and 10 before TDC.

Remember......timing marks on modified engines are not always accurate. Parts from this year and that year put together.

Check battery condition. Sounds partly flat to me OR the earth straps that should be from starter to engine OR earth strap from body to engine is not connected properly.

Simply connect volt meter to battery earth and earth on starter and crank....if more than 0.2v then earth circuit is faulty.

Repeat as above but from +ve battery terminal to +ve on starter.....must be less than 0.2v or faulty wiring on this circuit.

Testimonial: "Good things to be aware of."

SOURCE: i dont have power on a 89 camaro rs fuel pump

First of all you will only have voltage for 2 seconds after key is turned on from the fuel pump relay. after that when you begin to spin the engine over oil pressure then builds up and closes the contacts on the oil sending unit causing the fuel pump to stay powered up as long as it's spinning or it's crunk and running.
so while you check for power on the tan with white stripe at fuel pump , have someone bump the engine over, if you have power up until about 2 seconds after they let off the key then check ground to pump if it's ok then you'll need a fuel pump.
If you don't have voltage when it's spun over then check the red wire coming from the oil sending unit the same way you checked it at the fuel pump.
If you have voltage then check inline fuse beside the battery. if fuse is'nt blown then check for broken wire from there to fuel pump.
If you don't have voltage from red wire at oil sending unit then check for voltage on orange wire at sending unit, if you have voltage on the orange wire and not on the red wire while someone is spinning it over then replace the oil sending unit.
If you wanna do a quick check that makes sure your relay isn't the problem Go to your 12 way diagnostic connector under dash by stearing wheel. and touch a battery hot wire to pin G if relay is ok the you should hear the fuel pump come on.

simple the computer signals the injecters with negetive voltage approx.3 volts
