Im not sure how mechanically inclined you are but more than likely an ignition coil/coil assembly.underneath intake manifold.should be 3-14mm bolts or something of that sort.has 4ends for plug wires

    Yes, I agree that the coil or ignition module could also be the problem.

I have a 1990 Laser RS Turbo. Won't start, no spark at plugs but spark at coil. I hear a rapid clicking sound behind the radio on the passenger but all the time. When I try to start it it just turns...

normally a quick clicking sound means that the battery is low in voltage and amperage,but first check your connectors and the battery posts to make sure they are clean and secure. if you have a tester,check for voltage at the battery,you should be getting 12 volts or more.if you have 12 volts+,turn on the headlights and test the battery to see if it is retaining 12 volts or not,this is known as a load test. if voltage falls rapidly your battery should be changed.if it holds charge pretty well,than put thr battery on slow charge overnight and retry starting the vehicule.nb. the clicking noise is caused by the onboard computer that reads the voltage before startup and under 11.5 volts your car will make this sound.if your car starts put the tester on the battery again and check voltage,it should be 13volts or higher which means your alternator is charging the battery.

Will not accelerate fast without popping and sputtering, but will accelerated slow just fine

you have a miss fire under load the most common cause is a bad spak plug wire, if you give it a good old tune up it should take care of the problem.

spark plugs, spark plug wires, distabutor cap and rotor, air filter, fuel filter, and PCV valve.....good luck

My 1990 plymouth laser rs 2.0 liter turbo will start but dies if im not on the gas if i stay on the gas i can drive it but its slow to get up

This could be any number of things unfortunatley. I'd start with fuel pressure. Check the pressure. It could possibly be your fuel pressure regulator.

Suddenly started running rough like on one rotor as i was driving. heat gauge come on but was not overheating,no oil loss oil pressure fine spark fine no smoke, its a 1990 rx7 series5 13b turbo

ALL RX Engines are a 6cylinder as they have 2 triangle rotors with apex seals and 4 spark plugs but both rotors in both cylinders fire 3 times each and you have 2 rotors 2x3=6 ..Now if you are running on 1 bank which is 1 rotor then the other rotor isent working due to either the RED rubber seal band on either the front or centre housing OR the centre housing or the rear housing, has a leak and it must either be water or oil UNLESS its in the inlet manifold gasket leaking air in or the plugs on that rotor front or back , if the plug gap has closed up or oiled up .as there isent anything else i can think of .which could cause it.
Ihave built a few of these RX motors and they are without a turbo a lovely engine and go like s--- of a shovel get it going and dont get booked for speeding.. Let me know how you get on Ron

1990 300zx non turbo has miss on 2 cylinders

dude, i think you have two spark plug cables cross over. go to your local autozone and find a "firing order" if it was a blown head gasket it would show on the compression test but i'm pretty sure its a spark plug cable cross over.
