after about 6 messages and lots of response on a "fuel dist/pump" trouble link, i am still without a running car. have spark. newer pump from a non-turbo (i think, because it is smaller) now pumps fuel pretty fiercely, enough to open the injectors, but still no start. i am getting so frustrated. cranks over fine, all electrical fine, operable air flow plate, new plugs, new fuel filter. if anybody has a clue, could you call me (i'll call you back on my phone bill) and tell me where to look next? no-one in town has a volvo, so no-one knows how to work on them. i am to the point of sticking it on the street in front of my house with a for sale sign. i hate to give up on this project. help.

hi there, im pretty sure the fuel pump from lh volvo wont work on your turbo.
the k-jet system runs at about twice the fuel pressure.
i suggest to purchase the bentleys service manual (around 35.00$) and k-jet pressure tester (around 60.00$).
the pressure tester is very important with k-jet. there is a small screen at the control pressure regulator inlet thats possibly plugged , also possibly a ruptured diaphram. did you check the fuel pump relay? mine worked intermittently from a bad circuit board and bad six pin connector. did you check the lambda relay as suggested?
there is alot of different parts you can (throw) at this situation.
the answers are here in your previous posts but you need to take the suggestions one by one and report back on the results to each individual suggestion.
i dont have a money tree here either, but if i put a price on a repair without knowing what part i need i may never be able to reach my objective.
i know it can get frustrating, what helps me is not putting a time limit to my expectations. good luck

I had a 87 740 Turbo. I will tell you what I did and maybe it will help. I bypassed the turbo overboost cutoff. I disconnected the battery to reset the computer. I replaced the fuel pump relay. I replaced the fuel pressure regulator. This made it work for a year and then when it happened again I sold it. The final issue seemed to be related to the ignition switch. If the car didn't start in the first second of winding then I turned it all the way off and tried again. After 5 tries it would start. Two mechanics told me the car was fine when they tried it.
