Question is which brand of car you own.It is important to resolve your problem.Thank you.

Check for crushed/shorted wires. Check part numbers to verify model compatibility. If to no avail install aftermarket tachometer and turbo boost gauges.

Sounds like you want to restore it. Don't go to a garage. Take it to a restoration shop. They will restore anything, as long as you have the money to spend.

What ever it takes & whatever a shop want to charge you Get some prices & don't hold them to it

engine stalls. can be 50 reasons but are this. needs a 60k mile tune up bad. 1: EFI system has 12vdc power loss. (see dash dim?)_ 2: engine misfires. horribly and idle controls failed, (all will like that) 3: engine floods, same. 4: engine fueling drops so low and lean the engine stalls. 5: bad engine, cam time or sparking way off or 45 other engine prob. there is a test for each one, need a list? and last, 6: the ISC is stuck close, or EGR stuck open did you pull the DTC scan codes, the CEL blink test? from the ECU? is the CEL glowing (lamp in dash) running? omg, this is not a carb engine is it, many 87 were. 1987 is a cusp year, in USA for end off all carbs. (EPA rules)

Take off the heater hoses at the motor & usea garden hose to flush in both directions

You can go to Auto parts store and get a siphon kit that you don't have to swallow gas fumes.

You must start by checking the actual fuel pressure with a test gauge, the fuel test port is on the top of the engine in the fuel pipe that feeds the injectors, you can buy a universal fuel pressure test kit from Autozone. You must also run a electronic engine control fault code test, you can learn how to do that here.

Targa's are heavier than the solid roof supra cause the body panels are reinforced , cutting the roof to make a targa gonna weaken the structure greatly , if u gonna do it then theres a lot more to consider that just your saw blade, I got a 86.5 an with the roof off there's still body flex so be careful bro

Sounds like an internal problem with the compressor being too hard to turn.

Should be a designated fuse for the power to the fuel pump I'm not familuar with this model but some vehicals with electric fuel pumps have a reset swich on the pump or under the hood on the fire wall.

In the fuse box is a fuel pump relay, most relays are the same switch them around.

If the heater has a valve it will be located on one of the heater hoses.

I have the same problem with my other car I went to a repair shop but they'r asking
for $ 2500. What I did? I replaced the transmission for guaranted working one from surplus
parts seller now it works perfect. $500 for the transmission about $400 for installation. I save a lot...

sometimes the rubber bladder takes a dump and the outside of the pulley just comes off. if the whole pulley came off it sounds like the crank pulley bolt either was not tight or gone. if you recently had a timing belt replaced that might be what caused it.

if the ISC is bought brand new even though its new could go bad meaning it could be defective from the manufacturer from them from the start. You should also use a timing gun to check to see if the timing is where it should be at at idle speed of car. you could also use carb cleaner where it might be sticking at.

Check the wiring on the starter and alternator are in correct position, if fine than try to put the positive first, than switch on lights and try to put the negative on as second, if there is a problem with the electrical harness than you need a car electrician to have a look at it.

Radiator, usually comes on when the exterior plastic tank gets low . Sometimes these leak as a result from low antifreeze and the plastic tank will crac k at the base, where the wire comes out which activates the little symbol light to the left of the temp gauge you are referring to.

take the radiator cap off, only when engine is cool , start and turn the hater on high temp. once the engine thermostat has opened fill the radiator to top, replace cap. infront of the radiator in between the grille there is a small plastic reservoir, fill this to the proper level, also PS Make sure you add anti freeze and not just plain water it is best to purchase 50/50 mix as in the winter the plastic reservoir may freeze and crack without anti-freeze and you will be always adding water .
