I have an 87 range rover that does not start. I have checked timing, replaced the coil and just did a tune up 2k miles ago. I tried using starting fluid to start it, but nothing. It has good spark from the coil and plugs. When trying to start, I can smell gas in the engine compartment near the intake. Could you please let me know what else to check before I take it to a shop. Thanks for any help !!
