I have a 92 Pontiac Transport. When I last drove it the engine light came on then it quietly died - no chugging or missing - just smoothly lost power. Now it won't start. I checked the fuel pump and it spits out gas. I also have spark coming from the plugs. It cranks and turns over smoothly but just won't start. Can anyone help this single Granny? My garage in Canada wants $150 to scope it plus repair costs. If it is a simple sensor I can repair it myself. TY in advance Anna
