broncoll computer help?

ok guys i think my computers bad,replaced fuel pump,regulator,filter and all injectors are getting pulse but it wont start or run unless u spray starting fluid,and as soon as u stop spraying it dies,injectors were just cleaned a few months back when new tank,pump and filter were put on? so my question is does anybody have a known good computer for me to see if thats the problem that i can rent or buy to check it out? if not anybody know any place where i can get mine tested in or around the st.pete.florida area? or maybe some input on how to check the computer without buying one first? any help or leads are appreciated thnx bb oh and one more thing does anybody know what years and makes are compatible with mine? like will a 89 ranger computer work in place of mine and so on? thnx again and mine is a 1989 broncoll xlt 2.9 motor auto trans...

The computer pulses the ground to fire the computer. Unplug an injector do you have a hot on one side. Use a 12 volt test light. Then use a paper clip if you have 12 volt on one side does the test light blink when trying to crank. A bad fuel pump relay may be your problem. Get a loaner test gauge from Advance or Auto Zone verify you have fuel. The computer has a ground wire next to it make sure it is tight.

well according to the test light iam getting a pulse and it does blink when turning over,also i already had it tested for pressure it had a steady 40 while cranking and didnt lose pressure so i figure my regulators ok,so keeping all this in mind thats why we r figuring its the computer...so anyway to test em? or do i just have to go out and buy one? thnx

Ohm your injectors and use a stethoscope and listen to the injectors do they pulse.
Isn't your fuel pressure to high I'm retired but thought is was around 36psi.
If your injectors have pulse the plugs should have fuel.

my injectors have pulse and iam getting fuel to the plugs thats why im thinking computer? not sending firing signal? and according to alldata key on engine off psi is suppose to be 35-45 and 30-40 with enigine running like thats going to happen lol....so back to the computer i go any thoughts on diagnosing em or just replace?thnx

I think you replaced a head or intake. Injectors are like spark plugs they have to be plugged to the correct injector. All data has a picture of the color codes for the injector wires.
The computer pulses the injectors so the operate. You say the motor runs with fuel being sprayed in which indicates it is in time and the computer works. You say the injectors are being pulsed all of them. Check for a plugged air cleaner.

no i havent had the head or intake off in awhile,and the injectors were checked one at a time so no plug confusion.......and riddle me this...i was told that even though it will start when u spray into the throttle body that that part of the computer(igntion) is working but the other parts might not be.....is that right or not? and if it is or not can we get some opinions on if i can test the computer or not or just have to replace? thnx

When you spray into the throttle body the intake hose is disconnected. Check that you don't have plugged inlet somewhere filter or collapsed hose. If the injectors are getting pulsed you should be getting fuel to the plugs. Pull a plug and check if its damp. Also pull O2 sensor and check if it will start. Possible plugged CAT converter.
The computer has numbers on the back call a scrap yard. If it don't start with this I'm not sure what it is and can't help you.
Where did you check pressure on the fuel rail. Pull vacuum hose to regulator if full of gas replace.

thnx guys ill try the regulator tomorrow if that aint it ill buy another computer :(
