What exaclty does it do or doesn't do? Does it crank at all? If you washed the engine you need to make sure that there is no water between the valve covers where the sparkplugs are and that the distributor is also dry. If it doesn't crank at all check the battery cables and the battery itself, it should read around 12V.

i took cover off where spark plugs are and it was dry and i changed distribator cap and rotor button but it didnt help im getting fire from spark plugs and getting gas to fuel rail

An old trick, spray the distributor cap and maybe the dizzy itself with WD40. Read the can, "Displaces moisture". Supposedly WD40 stands for water displacement 40th attempt/mixture......

I would suggest U investigate the cold start injector/valve. My 87 was extremely difficult to start in cooler weather. The electrical connector was loose, but looked okay.

I discovered that problem after car sat for about 2, maybe three years, LOL.

i replaced the distributor cap and button it should be dry took each spark plug out they all are firing i tried spraying starter fluid in the intake but still nothing checked to see if they where power going to fuel injectors and they are and i also replaced coil

How much pressure do you have at the fuel rail? A clogged fuel filter or fuel pump going out might not be giving the injectors the pressure they need to spray.

ksbr77 · 01-04-2009, 09:42 PM

not really sure how much pressure i have no way to check i just took line loose and turned motor over and fuel squirted out i just replaced fuel pump and filter about three weeks ago drove for about 2 weeks and now it want even try to start

If that is the case then the only other thing I can think of is the cold start injector. Someone mentioned checking this earlier. If you're not sure what the cold start injector is it's here:

Hope this helps!

i checked cold start injector it isn't getting power to it but shouldn't it still fire if you spray starter fluid in the intake even when pump was bad you could get it to start like that after all thats basicaly what the cold start injector does i think i was talking to one of my friends he sujested flooding but dont think thats it either or you'd probley smell gas but you dont seems like if it was a sencor service engine lite would have came on but it didnt and i also got number 1 piston to top and looked at timming mark from what i could see it looked right but it is kinda hard to see where it is and checked distributor it checked out ok i thank you for your advice maticuno

To check the cold start injector, use an ohm meter and test it. It should read 3-5 ohms for a n/a.
