Hi Scotty, Need some advice on a 1989 Volvo 780 V6. Car starts great first thing in the morning. However, after I drive it for a while and attempt to restart it, it takes at least three tries before it starts. Car appears to be running rich as well. Replaced the fuel pump due to leakage and the fuel filter too. Also replaced the mass airflow sensor. Any thoughts on the issue or potential fix? I certainly would appreciate your guidance.

they often flood out when hot, try pressure cleaning the fuel injectors and realize you may need new ones

Thanks for the quick reply, much appreciated. Is pressure cleaning the injectors something a shop does with special equipment or can I do this myself with store bought supplies?
