98 E320 long crank when warmed up
hey, i know, this problem has been talked about before and i have read much about it. but the problem persists. car starts fine when cold. after its warmed up, if left to sit for twenty minutes it takes way to long to start, 6 cranks or more. i have replaced the cps, pulled injectors & had them rebuilt & tested. reinstalled with same results. so i took them out and had retested, shop said one was bad, replaced it with a new one. same results. pulled fuel rail with injectors in the rail and pressurized rail to 50 psi. watched for twenty minutes no visible leaks. so i pumped back up to 50 psi & heated each injector to about 180* F. & no leaks. installed back in the manifold, same results. also installed new fuel pump and filter. same results. the FP builds good pressure & will idle, accelerate all the time having 57 psi +/_ 2 #. any ideas of what is going on. any suggestions will be much appreciated
