96 Maxima, Hard Starting WHY??????

[samahi72]

My 96 with 86K on it starts hard. No service engine light on it but I it cranks and cranks longer than it should. Where should I start looking? It has new plugs, could it be a possible weak fuel pump? Could a dirty fuel filter cause it? Thanks.

Yes. also possibly bad coilpacks, MAF, crank angle sensor AND/OR their oxidized connectors/groundings. Check pressure with a gauge (feel it: hose stiffens under pressure.)

Start by checking voltage before/during start plus when engine running.
