Been working on a friends 85 Fiero with a 2.8 v-6. It has injector pulse and tach signal and spark and 45psi at the rail. I'm beating my head against a wall. I'm thinking injectors are bad. It was sitting for 5 years. Any way to possibly clean injectors?

Welcome to the Forum!

When you get a chance, play with the SEARCH function, and you will find 110 answers to your question, but the short answer is yes, and for a car that has been sitting 5 years, the injectors are surely stuck.

I searched no start but that all had to do with the pickup on the distributor. Ohh well. Thanks. I'm gonna order some new injectors. Which would you recommend as it's my first time working with fieros. I've worked on 3.4's and 3.8's but never 2.8's.

Injectors rarely go bad.....and cleaning is not expensive..so I would recommend that you send your injectors to a cleaning service....like the one in that link.

I'd be looking at over 100 for cleaning and testing and + shipping. Might as well look at getting rebuilt injectors if I can find any.

Does it have compression? Is timing correct? Did you check timing at TDC?

You may NOT have spark , even though you think that you do. Read my post within this thread and the results:

http://www.fiero.nl/forum/Forum2/HTML/130806.html

You may be able to fix your problem for just 15 minutes of your time if you have a KNOWN good replacement coil handy, or maybe just 15 minutes + $30 for a new coil. Much better than the 30 days + $300+ I spent before figuring this out, or your $100 + $?? + $??.

Check it out and get back to us. Best of luck, hope it works (again).

- Mark

Soaking the tips in injector cleaner will free them. You can activate them with a 9V battery. You should hear them click. You should be able to blow through them, slightly when activated. Don't leave power to the injectors for an extended period, you will burn out your injectors.

f85 is correct
there are 2 main trouble shooting technique
with strong battery
1=hook a spark plug gaped to .060 up to one of the distributor spark plug wires lay it on ground firmly,also run wire to block & spark plug
now if you have good hot red spark ! not weak tit yellow spark

2 = remove air cleaner snorkle, squirt fresh gas or starting fluid into TBI & attemp to start
have blanket or some method to stop possible fire
corrosion is a major factor in no start of a car that sits for years, the connector between the coil & distributor often have corrossion
if you know for certain a car was running when it was stopped normally the coil .pick up coil,module are O.K. the dist cap & rotor may be corroded
