it sounds like it's a spark or timing problem. if youre sure that youre firing at the right time, then see if your injectors are clogged, or maybe you have a few sticky valves. when the head gasket blew (which caused it to get oil and coolant together), you probably got alot of oil and coolant into your combustion chamber. this can deposit onto everything in there, causing a circus of problems, it can even foul your cat and 02 sensor. try some simple fuel additives after you replace your pump and check your injectors. also, do a compression check and see if youre normal and even in all of your cylinders.
