just wondering and trying to find out why my 90 DA isnt starting and was just wondering if it safe to pull the injectors and crank the engine to see if the injectors are the problem. if there is an easier way please let me know.

 

i would not do that. i would first verify that you have fuel pressure and spark and go from there

 

i have spark, the fuel pump pressurizes, and there is fuel in FPR. could i check the spark plugs to see if fuel is on them? the car will just crank but wont kick over and start.

 

what do you mean by fuel in the fpr? like fuel in the vaccum line connected to it

 

when i take the vacuum line off fuel comes out of both the line and from the fpr

 

if it does that the fuel pressure regulator is bad

 

ya that line is for vacume only and is what regulates the plunger in the regulator

 

ok so you have any good ideas on how to check to see if fuel is makin it to the cylinders. becuase im drawing blanks

 

Which line is it off of the FPR that contains fuel??? The fuel return line, or the vacuum, or both???

 

you could spray in some starting fluid and see if it does anything. i would replace the bad fpr and go from there


a generic drawing but shoudl get the idea across

 

vaccum so check return to see if fuel is coming back. ok

 

just hook up a fuel pressure gauge. checking the return to see if fuel is coming back wont help

 

if you really want to pull therail and injectors... you could. just letting you know ahead of time that the pressure will push the injectors off the rail.
