    starting problem when hot after setting for a while

    We boat in King George Va., mostly brackish water, not like the ocean or bay
  3. I have a 1999 Chaparral that will run fine when its cold, but after you let it set say for an hour, it will not start. If you open the engine cover and let it set for two hours, it will start again and run all day. Obvious its a heat related problem, and i have been told it needs a electric fuel pump booster and i have been told that the ECM is going bad, it there a way to pin point this problem. Would a OBD show codes codes left in the ECM from past failures or has anyone used the booster to solve the problem? The engine is a 0L356524 and is a 5.7L efi 350 and according to mercury they do not carry the ECM anymore, that sure was great to hear, there is a place in Calif. that i can optain one from for $1800. Sure could use some help on this problem, my boat mechanic seems to be somewhat stumped at this point, he has checked the fuel pressure and says its good. HELP!!!!!
